摘要: 該文針對(duì)多分量線性調(diào)頻(LFM)信號(hào)，首先提出一種新的變換RadonGabor變換；然后闡述了用RadonGabor變換對(duì)LFM信號(hào)進(jìn)行檢測(cè)和參數(shù)估計(jì)的基本原理,并結(jié)合逐次消去(Clean)技術(shù)提出了基于RadonGabor變換的多分量LFM信號(hào)檢測(cè)和參數(shù)估計(jì)實(shí)用算法。計(jì)算機(jī)仿真結(jié)果表明了該算法的有效性。Abstract: In this paper, a new transform called Radon-Gabor transform(RGT) is proposed firstly, then the basic theory is introduced for Linear Frequency-Modulated (LFM) signal detection and parameter estimation using Radon-Gabor transform. Moreover, a new method combining Radon-Gabor transform with clean technique for multicomponent LFM signal detection and parameter estimation is presented. The computer simulation results show its effectiveness.
