一种卫星导航抗干扰接收机的室内无线测试方法
An indoor wireless test method of GNSS anti-jamming receiver
摘要
Abstract
GNSS anti-jamming receiver indoor wireless anti-jamming test has the advantages of low cost,good controllability,strong repeatability etc,so it is used widely.Under the current indoor wireless anti-jamming test method,satellite signals use a single antenna output form and interference signals use the static interference simulation.The satellites' space position and the real interference scene can't be simulated,so the performance of GNSS anti-jamming receiver cannot be tested accurately.In order to solve the problem,a large field angle test method based on the microwave chamber is proposed,which achieves the satellite signals using multiple antenna output and the interference signals using dynamic interference simulation by expanding the range of the analog signals of viewing angle.According to comparing digital simulations with test results,the effectiveness and reasonability of the proposed method is verified,and the influence on the anti-jamming receiver performance test brought by the simulation error of signals is also analyzed.关键词
