Abstract
The lost pulse information due to pulse aliasing can lead to the worse radar sorting effect.For the problem,a novel algorithm of recovering the missing pulse information to complete the LFM radar signal sorting is proposed.First,the received LFM radar pulse signals are processed by wavelet transform.Then the time-frequency matrix binarization is realized by the method of contour.Secondly,the TOA of the pulse signal and the missing pulse signal because of time aliasing is detected and estimated.Finally,the sorting of LFM radar signals is completed based on PRI transform.Simulation results show that the algorithm pro-posed can detect the PRI values of each LFM radar,and the error of estimation maintain about 1% by recove-ring the information of the missing pulse.关键词
