相控阵雷达外场试验目标模拟技术研究

针对传统雷达回波模拟技术模拟目标态势单一、建设成本高、灵活性差等缺陷，结合相控阵雷达快速波束定向的扫描特点，提出了一种基于射频存储转发技术和移动阵列平台的相控阵雷达外场试验目标模拟方法。该方法采用射频空间辐射注入的方式为雷达提供较为逼真的三维空间模拟目标回波信号和构建较为复杂的模拟目标场景态势，能够支持包括雷达天线在内的整个雷达系统进行模拟试验或训练。最后通过实例仿真验证了该方法的有效性和可实现性。

Research on Target Simulation for Phased Array Radar Outfield Test

The traditional way of simulating technique has many problems, such as the oversimplified simulated target situation, the high cost, the bad flexibility, etc. Combined with the characteristic of the rapid beam orientation of the phased array radar, a new method of target simulation for phased array radar, base on digital RF memories (DRFM) and slide array platform, is proposed to solve the problems. This method provides more accurate echo signals and more complex simulated target scene by radiating electromagnetic signal in space, which can support the whole radar system test including the radar antenna. Simulation results prove the effectiveness and the viability.
