潜艇天线动态RCS的统计分析

Dynamic RCS Statistical Analysis of Submarine Antenna

潜艇的非声隐身性能近年来得到了一定重视,非声隐身的一个重要指标就是电磁隐身,而雷达散射截面(Radar Cross Section,RCS)表征了目标对照射电磁波的散射能力。天线一般处于舰艇的最高位置,它是被雷达探测的主要散射源之一,因而天线系统将直接影响到全舰雷达隐身性能。论文以潜艇鞭形天线为研究对象,以物理光学法(PO)为获取基础RCS的手段,并考虑了实际作战情况下与理想条件的不同,得到了不同于理想条件下天线RCS的统计数据,有助于提高获取目标RCS数据的完整性和可信度。

The non-acoustic stealth performance of submarines has been paid more attention in recent years.An important index of non-acoustic stealth is electromagnetic stealth and radar cross section（RCS）characterizes the scattering ability of target.Antenna is generally in the highest position of the ship.It is one of the main source of scattering,and thus the antenna system will directly affect the entire radar stealth performance.In this paper,the submarine whip antenna is taken as the research object,the physical optics（PO）is taken as the means to obtain the basic RCS,and the difference between actual combat situation and the ideal conditions is considered,the statistical data of the RCS of the antenna is different from that of the ideal condition,which helps to improve the integrity and credibility of the target RCS data.
