复合运动目标微多普勒特征的分析和提取
Micro-Doppler feature analysis and extraction of the complex motion target
摘要
Abstract
Micro-Doppler signature produced by micro-motion contains movement and structure information which is useful for radar classification and recognition.Because of the complexity and difference of micromotion, based on non-rotor targets and rotary-wing targets, the complex motion scattering point with translation,acceleration and vibration is modeled, so is complex motion scattering point with translation, vibration,acceleration and rotation.Then their micro-Doppler modulation and difference are analyzed.By simulation, the micro-Doppler modulation induced by the two models is extracted from the radar echo with the Smoothed pseudo Winger-Ville time-frequency analysis method, which agrees well with the computed results and proves that the models and the mathematical derivation of their micro-Doppler theoretical analysis are valid.关键词
