【摘要】：針對武器裝備發(fā)展對艦船目標(biāo)特性的需求,本文從電磁散射理論與雷達(dá)測試兩方面閘述雷達(dá)散射截面定義,表明了RCS在電磁散射理論和工程測量上概念是統(tǒng)一的。歸納岸基RCS測試的相對比較法,提出岸基雷達(dá)在掠海水平方向測試艦船RCS所需信噪比、采集數(shù)據(jù)量等要求,討論遠(yuǎn)場測試條件,規(guī)定了最遠(yuǎn)和最近測試距離,確保測試艦船RCS結(jié)果的準(zhǔn)確性。應(yīng)用統(tǒng)計方法對原始數(shù)據(jù)進(jìn)行處理,給出處理RCS均值、誤差、概率密度、累計分布函數(shù)等方法和應(yīng)用過程。本文提出的艦船RCS岸基測試方法,滿足武器裝備論證、試驗(yàn)鑒定等對艦船RCS應(yīng)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.
