Abstract: When synthesizing high resolution range profile for stepped-f requency radar , the desire for target ve-locity compensation accuracy is very rigorous. The high resolution range separation profile can be used to avoid this drawback. In this paper , firstly , some questions on the high resolution range separation profile are ana-lysed detailedly. Secondly , the mechanisms of angle measuring method based on high resolution separation profile is set forth. Then three angle measuring algorithm based on high resolution range separation profile un-der over-sampling conditions are developed and simulated. Computer simulation proves that the SLCE( select largest of cross ent ry) angle measuring method based on high resolution range separation profile is prior to the other two methods.
