摘要: 該文提出了一種脈沖壓縮的新方法匹配傅里葉脈沖壓縮技術(shù)。該方法可對(duì)多目標(biāo)回波在匹配傅里葉域?qū)崿F(xiàn)壓縮。壓縮回波峰值位置相對(duì)時(shí)延呈線性變化，從而使該方法與傳統(tǒng)的脈沖壓縮技術(shù)匹配濾波器脈沖壓縮一樣，可在雷達(dá)信號(hào)處理中應(yīng)用。文中首先給出匹配傅里葉脈沖壓縮理論和脈沖壓縮的回波時(shí)延分辨率，然后進(jìn)行理論仿真驗(yàn)證。仿真結(jié)果表明該理論是正確的，所提出的方法是可行的。

Abstract: A new method of pulse compression, match Fourier pulse compression technol-ogy is proposed in this paper. The method can achieve pulse compression to multi-targets echoes in match Fourier domain, and the peak position of each compressed echo changes linearly with its time delay. The same as conventional method of match filter pulse compres-sion, it can be applied to radar signal processing. The paper first gives the theory of match Fourier pulse compression and the resolution between echo time delays. Then the simulation is carried out. The results verify that the theory is right and the new method is feasible. -
