| 摘 要： | 接收相干算法为磁控管脉冲体制雷达实现动目标检测提供了依据。本文分析了几种相干接收处理算法,根据雷达系统结构和发射信号的特点,评述了各算法之间的适用性和优缺点,通过仿真分析研究各算法对MTI改善因子的限制。采用接收相干算法,可以实现准相参系统,其MTI性能不低于全相参雷达。

| Abstract: | Coherent-on-receiving processing （CORP） algorithm provides a basis for the magnetron pulse system radar to detect moving target. This paper analyzes several kinds of CORP algorithm. On basis of the radar system structure and characteristics of the transmitting signal, adaptability among algorithms and their advantages and dis- advantages are discussed. The limitations of each algorithm on MTI improvement factor are studied via simulation and analysis. Adopting coherent-on-receiving algorithm can implement quasi-coherent system, whose MTI perform- ance is not less than full coherent radar. |
