摘要
随着卫星导航系统在各行业的深入应用,抗干扰已成为衡量接收终端性能的重要指标。室外抗干扰测试作为检验终端抗干扰能力的重要手段,具有更大的实用价值逐渐被重视。本文通过分析抗干扰算法的复杂性以及室外测试的不确定性,提出一种基于定位精度评估的外场并行测试方法,并对测试过程中的环境构建、数据采集、数据评估等关键技术进行了详细阐述。最后,分析了静态和动态环境下的接收机测试结果,充分验证了测试方法的可行性和有效性。试验结果表明,静态和动态测试各有优势,两者结合可更准确的分析评估终端抗干扰性能。
With the wide use of satellite navigation system, anti-jamming capability is one of the important indices of receiver terminal. Anti-jamming performance test in the outdoor environment is considered the important measure of testing to show the actual value, so it attracts the extensive attention. The complexity of anti-jamming arithmetic and uncertainty of outdoor test are analyzed, the parallel outdoor test way based on the orientation precision evaluation is proposed. The key techniques such as environment composing, data collection and data evaluation are particularly explained during the course of testing. Finally, the test results of static and dynamic environment are analyzed to show the feasibility and availability of the test way. The experiment results indicate the static and dynamic tests are of different predominance and anti-jamming performance is exactly evaluated by the combination of the two ways.
