| Abstract: | The principle of LFM and step-frequency HRR technology are investigated in this paper.The performance of the LFM and step-frequency are compared in the stationary target case and moving target case.It is derived that for the stationary target,the HRR profiles gained by LFM and step-frequency are equivalent.And for the moving target,the range profile shifting and spreading gained by step-frequency is much greater than LFM. |
