【摘要】：针对武器装备发展对舰船目标特性的需求,本文从电磁散射理论与雷达测试两方面闸述雷达散射截面定义,表明了RCS在电磁散射理论和工程测量上概念是统一的。归纳岸基RCS测试的相对比较法,提出岸基雷达在掠海水平方向测试舰船RCS所需信噪比、采集数据量等要求,讨论远场测试条件,规定了最远和最近测试距离,确保测试舰船RCS结果的准确性。应用统计方法对原始数据进行处理,给出处理RCS均值、误差、概率密度、累计分布函数等方法和应用过程。本文提出的舰船RCS岸基测试方法,满足武器装备论证、试验鉴定等对舰船RCS应用要求。
[Abstract]:Aiming at the demand of weapon equipment development for ship target characteristics, this paper describes the definition of radar scattering cross section from two aspects of electromagnetic scattering theory and radar testing, which shows that RCS is unified in electromagnetic scattering theory and engineering measurement. The relative comparison method of shore based RCS testing is summarized. The requirements of signal-to-noise ratio (SNR) and data acquisition for shore based radar to test ship RCS in horizontal direction are put forward. The far-field test conditions are discussed, and the farthest and nearest test distances are defined. Ensure the accuracy of RCS test results. The statistical method is used to deal with the original data, and the methods and application process of processing RCS mean value, error, probability density and cumulative distribution function are given. The shore-based testing method of ship RCS proposed in this paper can meet the requirements of weapon equipment demonstration and test identification for the application of ship RCS.
