基于RCS序列的弹道导弹进动周期提取方法验证研究
The Verification of Precession Period Extraction Method of Ballistic Missile Based on RCS Sequence
摘要
Abstract
For the problems of the traditional method of micro feature extraction,such as low accuracy of data source,not considering the warhead translatory motion,the distributed authentication system of feature extraction is built and the commonly used precession period extraction method is verified.Firstly,the motion characteristic of the middle warhead and warhead radar cross section (RCS) template is generated by using the software of STK and FEKO.Secondly,the high-precision RCS sequence of warhead during middle course is generated by compositing the movement characteristics and the RCS template.Finally,the extraction effect of the common algorithm is verified based on the generated sequence.The simulation shows that the accuracy of pecession period extration method is not only subject to noise intensity but also closely related to the average aspect angle,the ACF algorithm gains more than two times accuracy than the CAUTOC algorithm when the average aspect angle is less than 35°.关键词
