Multicomponent LFM Signal Detection and Parameter Estimation Based on Discrete Match Fourier Transform

多分量LFM信号的检测和参数估计是一个被广泛讨论的问题。本文首先介绍了离散匹配傅立叶变换的基本原理,然后结合逐次消去的思想提出了基于离散匹配傅立叶变换的多分量LFM信号检测和参数估计的原理及实现算法,并进行了计算机仿真。仿真结果验证了该算法的有效性。

The detection and parameter retimation of multicomponent LFM signal is extensively discussed. In this paper, we firstly introduce the basic theroy of the discrete match Fourier transform (DMFT), then a new algorithm for multicomponent LFM signal detection and parameter estimation using DMFT is proposed. At last, this method is analyzed through extensive computer simulation. The simulation results show its effectivity.
