摘要
介绍一种距离维成像技术─—全去斜率处理技术的原理、关键问题以及飞行试验结果。该技术已成功地应用于逆合成孔径实验雷达的距离维成像。雷达发射带宽为４００ＭＨｚ的脉冲波线性调频信号，对其回波信号进行去斜率混频，再经ＦＦＴ处理即可得到实时的目标距离维像。
This paper introduces principle,key problem and flight test results of re-chirp processing,a technique of imaging in the dimension of radar range. This technique has been successfully used in range dimension imaging in an experimental ISAR. The radar transmits linear FM pulse signal with bandwidth of 400Hz and the real-time range dimension image of target is obtained by re-chirp processing,mixing echo signal and then by FFT processing.
