| Abstract: | Aiming at the impact of oppressive jamming on GPS signal acquisition and tracking, the feasibility of interference implementation in GPS receiver is analyzed.The GPS interference performance simulation is performed, and the mathematical model and simulation model of P-code GPS receiver,P-code GPS signal and GPS downlink channel are established.The anti-jamming tolerance of P-code GPS receiver is simulated and tested under single carrier interference signal,step wave sweeping interference signal and noise FM jamming signal.The simulation results are given and analyzed. |
