Modeling and Detection of Typical Complex Micro-motion Targets
摘要
Abstract
In order to detect the typical complex micro-motion targets in battlefield,a micro-motion targets detection method based on energy focusing is proposed. First,the models of three complex micro-targets are established and simulated,their frequency-domain and time-frequency domain characteristics are ana-lyzed,the frequency energy focusing characteristics of the echo time-frequency data are extracted. Then,a generalized likelihood ratio test( GLRT) detector for micro-motion targets based on energy focusing effi-ciency is proposed. The numerical simulation shows that the GLRT has a good performance under different echo signal-to-noise ratio( SNR) and false alarm probability conditions.关键词
