Precession Period Estimation of Ballistic Target in Midcourse
摘要
Abstract
To solve the problem that double misjudgment is caused when the circular average magnitude difference function( CAMDF) is used to estimate the precession cycle of the radar cross section( RCS) se―quence of the ballistic midcourse target,this paper introduces the concept of the convex hull function of av―erage amplitude difference function and proposes the convex hull circular average magnitude difference function(CHF-CAMDF) to process the RCS sequence of the ballistic midcourse target,and the business value of the lowest valley location and the sampling frequency are estimated as the precession period of bal―listic target. The simulation results show that CHF-CAMDF has obvious advantages in suppressing double misjudgment,anti-noise performance and sensitivity to the sequence length over the CAMDF. And CHF-CAMDF can effectively extract the precession cycle of the ballistic midcourse target,which provides a relia―ble basis for the identification of true and false warhead.关键词
