  • Critical Infrastructure Protection - Evaluating ITU-T G.9959 Based Wireless Systems Used in Critical Infrastructure Assets
    IFIP Advances in Information and Communication Technology, 2015
    Co-Authors: Christopher Badenhop, Joseph Hall, Jonathan D. Fuller, Benjamin W. Ramsey, Mason Rice
    Abstract:

    ITU-T G.9959 wireless connectivity is increasingly incorporated in the critical infrastructure. However, evaluating the robustness and security of commercially-available products based on this standard is challenging due to the closed-source nature of the transceiver and application designs. Given that ITU-T G.9959 transceivers are being used in smart grids, building security systems and safety sensors, the development of reliable, open-source tools would enhance the ability to monitor and secure ITU-T G.9959 networks. This chapter discusses the ITU-T G.9959 wireless standard and research on ITU-T G.9959 network security. An open-source, software-defined radio implementation of an ITU-T G.9959 protocol sniffer is used to explore several Passive Reconnaissance techniques and deduce the properties of active network devices. The experimental results show that some properties are observable regardless of whether or not encryption is used. In particular, the acknowledgment response times vary due to differences in vendor firmware implementations.

  • Network Radar Countermeasure Systems for Target Recognition
    Network Radar Countermeasure Systems, 2015
    Co-Authors: Qiuxi Jiang
    Abstract:

    A network radar countermeasure system for target recognition includes two aspects, one referring to the recognition of the radioactive target, namely, electronic target recognition, and the other referring to recognition of the target platform and its associated weapons systems. Some active radar can image the target, such as synthetic aperture or inverse synthetic aperture radar. They can also identify and recognize the target, but, in most cases, it is difficult to identify. Network radar countermeasure systems for target recognition mainly refers to recognition of the radiation source and its loaded platform or associated weapons systems with Passive Reconnaissance signals. Because the network radar system is compatible with the ability to identify friend or foe, it can also identify friend and foe on the battlefield. At the same time, if active detection of the target speed information is increased, then the identification of the target attributes will become more reliable.

  • Target Positioning of Network Radar Countermeasure Systems
    Network Radar Countermeasure Systems, 2015
    Co-Authors: Qiuxi Jiang
    Abstract:

    The network radar countermeasure system can be divided into the following: active detection mode, Passive Reconnaissance mode, and active Passive integrated mode. In each mode, the principle and process of target location are different. When working in an active detection mode, the system will use the target to detect and locate the echo signal of transmitting signals and the receiving station can obtain the target state quantity measurement information, including target arrival time (TOA, or range and angle), information (azimuth and elevation), Doppler, etc. At this point, the system has strong abilities in target positioning; when working in a Passive detection mode, the system can locate the target by intercepting the target radiation signal. The moving state quantity measuring information intercepted by the receiving station includes the measuring pulse arrival time (TOA), the angle information (azimuth and elevation), and target attribute quantity measurement information (the radiation source frequency, pulse width, antenna scanning frequency, pulse cycle, pulse characteristic information, etc.). The positioning accuracy depends on the system configuration and the accuracy of the time difference.

  • Research of vehicular laser Passive Reconnaissance warning system
    Infrared and Laser Engineering, 2003
    Co-Authors: Ge Qiang
    Abstract:

    The development and actuality of laser Passive Reconnaissance warning device are sketched. The composition, operation principle and features of the system are introduced. The design of laser probe and data processor of the laser warning device are emphasized. InGaAs Pin photodiode is adopted in the optoelectronic detector of the probe. The data processor comprises threshold circuit, discrimination circuit of pulse bandwidth and twoecho signal restraining circuit. Firstly, the laser signal is digitized under the condition that the signal is affirmed. Then the incident orientation of laser is calculated. Finally, the laser ranging signal and guiding signal are distinguished by threat style and grade curcuit on the basis of threat database. The system has the advantages of high sensitivity, rapid response and wide dynamic range, and it can be linked up with smoke discharging equipment. The system and other defense equipments can be connected by preparatory communication interface. 
