[Abstract]:With the development of (Global Navigation Satellite System,GNSS (Global Navigation Satellite system), the high-precision positioning and navigation performance of GNSS has been widely used, especially in military aspects, such as unmanned aerial vehicles, combat vessels, submarines, cruise missiles and ballistic missiles, etc. Therefore, the navigation countermeasure technology related to the global navigation system has aroused the attention of many countries. At present, the research of navigation countermeasure technology is mainly focused on jamming the navigation positioning signal, thus destroying its positioning and navigation function. In this paper, the channel simulator in the technique of navigation countermeasure-repeater spoofing jamming is studied and realized. Based on the full investigation and analysis of the current navigation countermeasure technology and channel simulation technology, this paper focuses on the problems of partial theory, poor implementation, and mainly focused on the field of mobile communication, for the existing navigation countermeasure technology research, such as partial theory, poor implementation, and so on. This paper proposes to realize repeater deception jamming by changing the corresponding channel characteristics of navigation signals. Based on the research and analysis of navigation signal structure, positioning principle and the influence of channel characteristics on navigation signal, a jamming model is established, and according to the functional requirements of channel simulator in the model, a jamming model is established. The overall implementation scheme of the channel simulator is proposed. The simulation algorithm of channel characteristics, the signal processing module of channel simulator and the control software of channel simulator are provided in detail. Considering the nonlinear characteristics of the receiving frequency, the third-order DDS is used to simulate the carrier Doppler. The FPGA chip is used as the signal processing module of the channel simulator to simulate the channel characteristics of if navigation signal such as Doppler frequency shift delay and so on. At the same time the channel simulator control software is used to control it in real time in the form of parameters. Finally, after the overall design and implementation of the channel simulator, the performance test is carried out to verify the simulation effect of the channel characteristics. It includes synchronization of different channel output, relative delay, Doppler frequency offset test and the overall function test of the channel simulator. The test results show that the channel simulator designed in this paper can correctly simulate the channel characteristics such as relative delay and Doppler frequency shift of navigation signals, and successfully generate deceptive signals to achieve repeatable deception jamming.
