A detailed analysis is made on the echos Doppler spread and range spread caused by body target spread, and on their influence on ranging.
从理论上分析了由于体目标引起的引信回波信号的多普勒展宽和距离展宽问题，以及它们对近距离扩频测距的影响。
First, each range resolving unit was accumulated non-inherently in azimuth, and then the detection of HRR target was done with the GLRT detector similar to that of the mono-pulse spread targets.
该方法首先对各距离分辨单元在方位向进行非相参积累，然后利用类似单个脉冲下扩展目标的广义似然比检测器来实现高分辨率雷达的检测。
