舰船 RCS岸基测试与数据处理方法

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。

Ship RCS shore test and data processing method

Aiming at the requirement of the development of weapon equipment, in this paper, the definition of the radar cross section area is defined from two aspects of electromagnetic scattering theory and radar testing, which shows that the concept of RCS is unified in the theory of electromagnetic scattering and the measurement. This paper summarizes therelat-ive comparison method based RCS test, the shore based radar in test ship sea skimming horizontal direction required signal-to-noise radioacquisition data volume and other requirements. The far field test conditions, specifies the most distant andre-cent test distance, the accuracy of the ship RCS test results. The methods and application of processing RCS meanerrorprob-ability density and cumulative distribution function are given. Ship shore RCS test method proposed in this paper, to meet the weapons and equipment verification and testing requirements for ship RCS application in the end.
