Anti UAV system (mobile platform emitter location system)

Author:Wuhan luowave Co., Ltd Click:

     The emitter location system of mobile platform uses mobile single station to locate the emitter such as communication radio and radar. The system can detect and locate a wide range of frequency signals, monitor the signals of interest, capture weak signals better, eliminate the multipath effect caused by NLOS ships in various environments such as cities, suburbs and villages, and realize the real-time positioning of the number and location of radiation sources and the real-time display of the map, so as to provide users with the surrounding electromagnetic environment information. The system has the characteristics of high positioning accuracy, high sensitivity, light weight, low power and a variety of deployment structures, which is very suitable for the use of mobile conditions (personal carrying or vehicle mounted).

    The system consists of antenna, usrp-lw N210, ubx-lw, GPS positioning module and signal processing module, as shown in the figure below. When the system moves, the antenna receives the signal of the target emitter in the environment. The GPS positioning module records the longitude and latitude information every specified time, and triggers usrp-lwn210 to collect the field strength value at the moment. According to the field strength value at different positions at different times, the number and location of radiation sources can be located according to the corresponding positioning algorithm.

    The system can capture the weak signal and solve the problem of poor positioning accuracy in complex multipath environment on the ground. The following is the effect video of positioning UAV and UAV operator under vehicle conditions. The system can accurately perceive the UAV map transmission and remote control signal strength of the driving road, and call the surrounding map to accurately locate the number of UAVs and unmanned remote control and mark their geographical location. So it is helpful for users to find UAV and unmanned operator conveniently and quickly.
