Research of hardware-in-loop simulation test for interferometer's passive location performance

针对测试干涉仪的无源定位性能通常采用的实测法和电子模拟法存在的不足,提出了一种半实物仿真测试方法.该方法利用航空电子系统射频综合仿真重点实验室中的暗室、转台、阵列控制系统、飞行仿真系统等设备模拟外场试飞场景进行干涉仪无源定位仿真测试试验.通过对试验数据的分析,验证了该方法不仅能够全面、准确地测试干涉仪的定位性能,而且试验成本低、重复性高,试验结果能够用于指导干涉仪的研制,具有较高的应用价值.

Aimed at the shortcoming existing in the field measurement method and electronic analogue method for interferometer＇ s passive location performance test, this paper puts forward a type of hardware-in-loop simulation test method. In this scheme, the darkroom, the rotary table, the array control system, the fight simulation system and other equipment in the key laboratory on RF avionics system comprehensive simulation are employed to simulate the field test flight scene, for testing the interferometer＇ s passive location performance. By analyzing the test data, it is verified that this method can not only assess the interferometer＇ s location performance overall and accurately, but also be of low test cost, high repeatability, and the test results can be used for directing fast the development of interferometers, which have a higher application.
