Analysis of Micro-Doppler Effect of Armored Vehicle Based on Adaptive Optimal Kernel Time-frequency Distribution
摘要
Abstract
An echo signal model of armored target is established by micro-motion line target model based on micro-doppler effect in this paper,for the non-stationary and nonlinear echo signal,feature parameters of echo signal can be extracted by adaptive optimal kernel time-frequency distribution (AOK TFR)and ridges-computed method. Simulation results show that the method is evidently better than point target model and other time-frequency methods,and the influences of different feature parameters such as the length of gun barrel and acceleration of vehicle on micro-doppler features at low signal-to-noise ratio is analyzed.关键词
