摘要
分析了LFM和步进频雷达体制的成像原理,对两种成像体制的性能进行了比较,通过比较可以得到,对于静止目标,两者的成像结果是相当的,但对运动目标,步进频体制下目标运动引起的距离像的平移和展宽比较明显.
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.
