摘要: 該文提出了一種星載極化SAR分布目標原始數(shù)據(jù)模擬和仿真方法。在引入極化后向散射矩陣的基礎上，介紹了分布目標后向散射系數(shù)的計算方法，詳細闡述了極化原始數(shù)據(jù)產(chǎn)生過程。最后通過對模擬得到的極化原始數(shù)據(jù)的仿真再現(xiàn)圖像分析，證實了對星載SAR極化原始數(shù)據(jù)模擬的正確性。

Abstract: In this paper, a method that is used to simulate distributed targets raw data of spaceborne polarization SAR is given. Based on the backscattering polarization matrix, the algorithm of computing distributed target backscattering coefficients is discussed. Then the process of obtaining the raw data is particularly introduced. Through analyzing the image that come from the simulated data, the conclusion can be reached that the method of simulating the polarization raw data of Spaceborne SAR is right. -
