一种基于稀疏分解的微多普勒频率估计算法
A Method of Micro Doppler Frequency Estimation Based on Sparse Decomposition
摘要
Abstract
Analysis of the target method and micro Doppler features plays an important role in the target recognition. Due to the characteristics of nonlinear, multicomponent of micro target radar echo, the analysis tools of dynamic range high resolu-tion and low cross terms are needed, which can receal the micro Doppler features of target. In this paper, the micro Dop-pler frequency estimation based on matching pursuit (MP) for its high frequency solution and good effect of subtle features extraction was studied. This method can accurately extract micro Doppler frequency and provide an important basis for the subsequent target identification.关键词
