  • Optical fiber connected passive primary Surveillance Radar using two receiver units
    2017 International Symposium on Antennas and Propagation (ISAP), 2017
    Co-Authors: Junichi Honda, Masato Watanabe, Takuya Otsuyama
    Abstract:

    This paper describes a concept of multi-static primary Surveillance Radar (MSPSR) developed by ENRI. We have so far proposed an optical fiber connected passive primary Surveillance Radar (OFC-PPSR) which is based on the principle of passive bistatic Radar. A separated receiver unit uses scattered waves from aircraft and Radar reference data transmitted by the radio over fiber (RoF). Radio frequency signals of transmitter unit and processing data such as rotating angle, transmitted timing and so on, are included as reference data. In this paper, we introduce the proposed system which consists of two receiver units. Then, we show a preliminary experimental result. It will be shown that the proposed system detects the moving object.

  • Study of passive aircraft Surveillance Radar using DTTB signal delay
    2016 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2016
    Co-Authors: Takuya Otsuyama, Junichi Honda
    Abstract:

    The current Air Traffic Management uses various Radar or Radar like systems. However, the conventional Primary Surveillance Radar (PSR) have a high cost of the maintenance and the operation in comparison with usage. Recently, Multi-Static Primary Surveillance Radar (MSPSR) has attracted interest from the civil aviation research field. The MSPSR system is to use not just the conventional PSR signals, but also other radio waves, such as Digital Terrestrial Television, GNSS and cellar. Thus, MSPSR have the possibility to reduce the maintenance and the operation cost of PSR system. In this paper described the experimental results of aircraft detecting by using terrestrial digital broadcasting signal delay. It will be shown that the proposed calculation method is useful for detection of the aircraft.

  • Experimental results of aircraft positioning based on passive primary Surveillance Radar
    2014 Tyrrhenian International Workshop on Digital Communications - Enhanced Surveillance of Aircraft and Vehicles (TIWDC ESAV), 2014
    Co-Authors: Junichi Honda, Takuya Otsuyama
    Abstract:

    This paper describes an activity of passive Surveillance system in Japan. Electric Navigation Research Institute (ENRI) started the feasibility study of the passive Surveillance system to be a conventional primary Surveillance Radar (PSR) alternative. The representative system among its technologies is a multi-static primary Surveillance Radar (MSPSR) which achieves higher update rates and higher detection rates including low level flights than those of the current PSR. The MSPSR is classified into passive bi-static Radar (PBR), and it is operated by combining some transmitters or some receivers. Radio waves of the conventional PSR are suitable resources of operating frequency. Therefore, ENRI has investigated passive PSR. In this paper, we introduce our recent works and show some results of experiments carried out in the Sendai and Nagoya areas in Japan. In the experiments, we investigated the advantages of the passive PSR. First, we introduce experimental environment and experimental setup. Next, we show experimental results. Results show high performance of the passive PSR system where the passive secondary Surveillance Radar (SSR) was unable to carry out positioning. Finally, we discuss the passive PSR potential.

  • A study of direction finding method for passive airport Surveillance Radar
    2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014
    Co-Authors: Takuya Otsuyama, Junichi Honda
    Abstract:

    The current Air Traffic Management (ATM) uses various radio equipment. The Radar is the one of important system and the recent ATM uses a combination of several Radar systems. However, the conventional Primary Surveillance Radar have a high cost of maintenance and operation. Recently, Multi-Static Primary Surveillance Radar (MSPSR) has attracted interest from the civil aviation research field. The MSPSR is classified into passive bistatic Radar (PBR). In this paper, we discussed receiver side direction finding method (DF) for the passive PSR system. This method is required for MSPSR. We show the DF method based on interferometer and experimental results, and we discussed the potential of DF for the passive PSR system.

  • Algorithms to separate overlapping secondary Surveillance Radar replies
    2004 IEEE International Conference on Acoustics Speech and Signal Processing, 2004
    Co-Authors: N. Petrochilos, A.j. Van Der Veen
    Abstract:

    We investigate the separation of a linear mixture of secondary Surveillance Radar (SSR) replies impinging on an M-element antenna array. At base-band, a received SSR signal consists of a binary sequence with alphabet {0, 1}, modulated by a complex exponential due to the residual carrier frequency. We present two algebraic algorithms to compute the separating beamformers by taking into account the particular modulation format of the received signal.

  • Secondary Surveillance Radar for RSP-10M system
    2018 28th International Conference Radioelektronika (RADIOELEKTRONIKA), 2018
    Co-Authors: Vadim Zavodny, Pavel Bezousek, Vladimir Schejbal
    Abstract:

    This paper explains the upgrading of the Russian RSP-10 Radar system, which is still employed by several customers. The main topic is the incorporation of the ICAO secondary Radar system into the system combining the primary Surveillance Radar antenna at L band, ICAO and Russian UVD standard. The design uses a phased antenna array that make up the SUM and DIF antenna pattern. These patterns are shaped by common reflector antenna. The correct separation of the side lobes between the SUM and DIF beams in the ICAO band will ensure the OMNI antenna. The UVD standard uses an antenna array with three dipole elements that works as receiving part of the UVD.

  • Primary Surveillance Radar of RSP-10M system
    2018 28th International Conference Radioelektronika (RADIOELEKTRONIKA), 2018
    Co-Authors: Vadim Zavodny, Vladimir Schejbal, Pavel Bezousek
    Abstract:

    This paper describes the modernization of the RSP-10 Radar systems, produced in Russia, which are still operated by several users. We describe the modernization of this system, which includes a new Radar design, comprising an antenna unit, an air-conditioned container with control and power electronics, and an original primary Surveillance Radar antenna unit. The paper is concentrated on the new very challenging design of the three-band antenna unit combining primary Surveillance Radar for L-band (1250-1350) MHz, secondary Surveillance Radar of ICAO (1030, 1090) MHz, and UVD 740MHz for transportable system. Due to the limited extent of the paper, mainly the L-band antenna design is described.

  • Secondary Surveillance Radar Antenna [Antenna Designer's Notebook]
    IEEE Antennas and Propagation Magazine, 2013
    Co-Authors: Vladimir Schejbal, Pavel Bezousek, Jan Pidanic, Milan Chyba
    Abstract:

    This paper deals with a secondary Surveillance Radar (SSR) array antenna, which is intended for a system combining the secondary Surveillance Radar antenna and the primary Surveillance Radar antenna. It describes the patch array elements and the synthesis for the secondary Surveillance Radar array, considering both elevation and azimuth patterns for sum, difference, and sidelobe-suppression beams, and suspended stripline couplers. The utilization of multilayer techniques allows the connection of layers with patch radiating elements and layers with beamforming networks.

  • Fusion of tri-dimensional Surveillance Radar data
    2006 9th International Conference on Information Fusion, 2006
    Co-Authors: A. Di Lallo, A. Farina, R. Fulcoli, A. Stile, L. Timmoneri, D. Vigilante
    Abstract:

    The paper deals with the problem of impact point prediction of ballistic targets (BT) by processing measurements acquired by two 3D Surveillance Radars. It is assumed that the Radars acquire a limited number of measurements that do not encompass the whole target trajectory; thus the established target track has to be extrapolated ahead in time in order to predict the coordinates of the impact point. The updating and testing of the data extractor (DE) of a notional tri-dimensional Surveillance Radar system is presented in this paper; the modified hardware and software is capable of acquiring, managing and fusing tracks pertaining to the Radar system housing the DE and to other systems connected to the DE itself

    Abstract:

    The paper deals with the problem of impact point prediction of Ballistic Targets (BT) by processing measurements acquired by two 3D Surveillance Radars. It is assumed that the Radars acquire a limited number of measurements that do not encompass the whole target trajectory; thus the established target track has to be extrapolated ahead in time in order to predict the coordinates of the impact point. The updating and testing of the data extractor (DE) of a notional tri-dimensional Surveillance Radar system is presented in this paper; the modified hardware and software is capable of acquiring, managing and fusing tracks pertaining to the Radar system housing the DE and to other systems connected to the DE itself.
