Construction method of wide angle test scenario for satellite navigation receiver based on anechoic chamber

Guo Shuxia; Zhang Ning; Yuan Chunjuan

A construction method of wide angle test scenario based on the anechoic chamber was proposed. Utilizing the existing 42 RF array, the amplitude and phase of signals arriving at the receiver from array antenna units were calibrated by multi-state joint calibration. And by gray relational analysis principles, the proposed method achieved the approximately true mapping satellite constellation and dynamic interference in the anechoic chamber. So the semi-physical anti-jamming test environment whose largest field angle was 160 was constructed. Simulation and test results show that the maximal deviation between antenna units in the anechoic chamber and the angular domain of the satellite constellations in the real scene is within high gain 3 dB beam width, and the power needed for dynamic interference to arrive at the receiver is approximately the same whether at actual scene or under simulation in anechoic chamber. Lastly, the anti-jamming test of multi-beam receiver was completed, the relation curves of J/S and C/N0 were given, indicating that the proposed method can not only effectively simulate the outfield test scenario of satellite navigation receiver indoors, but also accurately test the performance of multibeam anti-jamming receiver.
