对于以磁控管雷达为代表的功率振荡式雷达,一般采用接收机相参方法实现动目标检测。褶积处理和互相关处理是两种新的接收机相参方法,可以不同程度地提高系统改善因子。本文指出了它们各自的主要问题,并针对这些问题提出了一种褶积-互相关复合处理方法,这种方法对波形和AFC静差要求不高,并且,几乎可以完全消除发射机不稳对改善因子的限制。预计,采用这种新技术后、一部磁控管雷达的系统改善因子不低于同波段的任何一部全相参雷达。
For the power oscillation radar represented by magnetron radar, the moving target detection is generally implemented by the receiver coherent method. Convolution and cross-correlation processing are two new receiver coherent methods that can improve the system improvement factor to varying degrees. This paper points out their main problems, and proposes a convolution-crosscorrelation complex processing method for these problems. This method has less requirements on the waveform and AFC static difference, and can almost eliminate the unsteady transmitter Limit the improvement factor. It is estimated that with this new technology, the improvement factor of a magnetron radar system is not lower than any of the coherent radar with the same band.
