摘要：
In stretching processing system of linear FM, the frequency is in proportion to range and the delay of returns are different in different ranges. The single frequency pulses occupy different time intervals indicating the variation in time delay as a function of range after stretching processing. This will lead to high sidelobe when proceeding with a uniform weight in the whole time width. This paper describes a method of delay compensation with subband filter group. Sidelobe level of weighted signal will be greatly reduced after the synthesis of multiple channels.
