说明： 角度间隔分别为0.5°和0.3256°,方位样点数分别为47和404.3种飞机的数据长度均为64个距离单元(Range cell),所得随方位角变化的一维距离像CJFD2004

这时需要分距离单元进行时频分析，得到距离-瞬时多普勒图像。
In this case, time frequency analysis must be performed for every range cell to obtain range instantaneous Doppler (RID) image.
该方法利用每个距离单元的相位历程中所含大幅度的线性调频分量进行成像。
This approach develops images from linear frequency modulation components that are included in the phase history in every range bin.
常规单脉冲雷达对落在同一距离单元、同一波束内的多个目标是难以区分的。
It is hard to distinguish the multiple targets located in one resolution cell and the same beam with normal monopulse radar.
