直升机运动状态下雷达回波建模与微动特性分析
Modeling of radar echoes of helicopter in motion state and analysis on its micro-motion characteristics
摘要
Abstract
The conventional radar echo modeling of helicopter does not consider the effect of its own attitude change on the echoes when the helicopter moves,which results in the inconsistent simulation results with the reali-ty.In order to solve the above problem,this paper is based on the scattering point echo model of rotor blades in free space,and introduces multiple parameter matrices and vectors to realize the construction of a unified radar echo model under helicopter motion,and then theoretically analyzes the variation of helicopter echo micro-motion characteristics under different motion states.The simulation results verify the correctness of the theoretical analy-sis,and show that the change of motion state will produce effect on the radar echo of helicopter.The study in this paper has certain value for the development of helicopter target recognition and intention recognition.关键词
