基于高阶矩函数的雷达目标微动参数估计方法
Micro-Motion Parameter Estimation of Radar Target Based on High-Order Moment Function
摘要
Abstract
A method for micro-motion parameter estimation of radar target based on high-order moment function is present-ed ,which is suitable for the narrowband radar .Firstly ,the radar echo is mixed with the reference signal ,and then its direct current is eliminated .The high-order moment function of the signal with different time delays is calculated firstly ,then the Fourier transform results of the high-order moment′s imaginary parts are calculated and the peak value of their product results is detected to obtain the rotation frequency of target′s micro-motional parts .The radius and the initial phase are estimated by successive cancellation .A com-puter simulation is given to illustrate the effectiveness of the proposed method .关键词
