一种新型的机载雷达射频仿真系统设计方案

A Novel Project on Radio Frequency Simulation System of Airborne Radar

用现有的射频仿真方法实现机载雷达仿真,为满足远场条件,将导致暗室尺寸过大等一系列问题。论文提出了一套新型的机载雷达射频仿真系统设计方案,该方案可以大大缩减微波暗室的建造尺寸和成本,并且有视场角大、静区特性较好、控制结构简单等特点。并对影响目标位置精度的各因素进行了分析。

On past research on airborne radar simulation, a series of difficulties are encountered because the size of the requested microwave anechoic chamber under the far-field condition is too big with the current methods. The novel project presented in this paper will show how to deal effectively with these difficulties. On section 2 and 3, it is discussed in detail about how to reduce the size of the microwave anechoic chamber, while the bigger field-of-view, the better quiet region and the simpler control can be got. The analysis of the target positioning error is also presented in section 4.
