波束方向探测技术的注入式仿真系统验证

这篇文章主要介绍采用功率探测仪方式的注入式仿真系统对波束方向地面探测试验系统进行验证的系统设计和软、硬件控制与实现。通过向注入式仿真系统输入模拟目标星在不同位置发射的信号功率，以及目标星在平台坐标下的角度和位置信息，一方面确定地面探测试验系统技术方案的可行性和检测相关设备的性能，另一方面验证对目标星发射天线主波束方向的探测是否满足精度要求。通过仿真试验证明该注入式仿真系统不仅使用方便、节约成本，而且通过控制相关仪器设备能够准确记录地面探测试验系统对目标星仿真数据的计算信息，进而实现验证。

Injection Simulation System Test of Beam Direction Detecting Technology

It describes the system design and software and hardware control and realization of a ground-based beam direction detecting system which is verified through injection simulation system by using power detector in this article. Through inputting simulated power signal from different satellite positions, and angle and position information of target satellite in the platform coordinates system into the injection simulation system, on one hand the ground-based detecting system technical solution feasibility can be defined and relevant detecting devices tested, on the other hand it can verify whether the detection capability against target satellite transmission antenna main lobe can meet the accuracy requirement. The simulation test results have proved the facts that the injection simulation system is easy for operation and cost effective, and through controlling relevant devices can it also record accurately the calculation information on target satellite simulation data which is carried out by the ground-based detecting system.
