The range image with high resolution of sea-skimming target is a very important research direction. This paper presents a method of radar range imaging based on dechirping receive technology. This method combined the dechirping receive technology with speed of target motion compensation. By using DSPA digital pulse compression and Hamming weighting algorithm, the method may not only reduce bandwidth of return signal, but also decrease sidelobe level of target range. Combined with radar outdoor dynamic measurement, one dimension range imaging of ships is obtained. The measured result shown that this method can provide an effective way for dimension range imaging of outdoor radar target.
