摘要
Stepped frequency radar waveform is put forward for improving the accuracy of radio fuze ranging. IFFT is adopted to synthesize one dimension high resolution range profile. Furthermore, the same range reject method and selection maximum method are made use of removing target redundancy and the simulation results are given. Characters of the two methods are analyzed, and under the proposal of Weibull distribution clutter envelope, the CFAR same range selection maximum method is adopted and realizes the accurate profile and ranging.
