| 摘要: |
| 针对空间目标飞行速度快、轨道高度高、真假目标伴随运行等的特点,空间探测相控阵雷达(SSPA)应该具有作用距离远、测量精度高的特点,并具有相应的多目标识别能力.文中简要介绍了一种空间探测相控阵雷达仿真系统的结构和工作原理,并对其中的信号处理子系统进行了分析.为了使其具有多目标处理能力,信号处理子仿真系统的恒虚警和解模糊算法分别采用排序统计恒虚警和余差查表法.最后以一组数据为例给出了仿真结果. |

| () |
| Abstract: |
| Targets in space are characterized by fast flying velocity, high orbit and usually traveling with false targets. Accordingly, a Space Surveillance Phased Array(SSPA) radar should have a far instrumentation range, high measurement precision and the ability to identify multiple targets. This paper simply introduces the structure and working principles of a SSPA radar simulation system, and analyzes the Signal Processing(SP) sub-system. To make the SP sub-system be able to process multiple targets, OS-CFAR and Residues difference look-up table method are respectively adopted as the algorithm of CFAR and ambiguity resolving. Finally simulation results are presented. |
