窄带雷达观测下的锥体目标参数估计方法
Parameter estimation method for the cone-shaped target under narrow-band radar observation
摘要
Abstract
The parameter estimation for the space cone‐shaped target based on precession is very important for target discrimination . This paper proposes a novel parameter estimation method via the scattering centers' micro‐Doppler frequency contained in the narrowband echo . After the establishment of the target's precession model , the theoretical variation of top and bottom scattering centers' micro‐Doppler frequency are derived , and then the micro‐Doppler frequency of the bottom scattering center is expanded , and the relationship between the expansion coefficients and the target's size and precession parameter is analyzed . Finally , a linear system of equations is established to solve the expansion coefficients with the top and bottom scattering centers' micro‐Doppler frequencies , and then the target's size and precession parameters are calculated based on the coefficients . Experiments based on electromagnetic computation data indicate that the proposed method is valid and accurate .关键词
