摘要: 该文针对多分量线性调频(LFM)信号，首先提出一种新的变换RadonGabor变换；然后阐述了用RadonGabor变换对LFM信号进行检测和参数估计的基本原理,并结合逐次消去(Clean)技术提出了基于RadonGabor变换的多分量LFM信号检测和参数估计实用算法。计算机仿真结果表明了该算法的有效性。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.
