簡介：CCD航天光學遙感相機的成像與傳統(tǒng)的膠片成像有著很大的差異，膠片的顆粒度相對于光學系統(tǒng)彌散斑來說它的大小可以忽略，而CCD探測器的像元尺寸一般來說是光學系統(tǒng)彌散斑的幾倍，把以CCD探測器為接收器的光學成像系統(tǒng)看作是空間移不變系統(tǒng)會帶來一定的理論上的近似，因而在理論上不能準確求得分辨力與像質(zhì)的關系，所以在實踐中又采用了平均意義的MTF。這里則采用模擬試驗及計算機仿真的方法來研究在空間移變條件下的CCD遙感相機的影像分辨力和像質(zhì)問題，這種研究不僅在理論上是一種補充，在工程實踐上也很有實際意義。鑒于CCD探測器成像是數(shù)字化成像，所以本文采用計算機仿真和CCD相機模擬成像試驗及理論分析的方法對CCD探測器的目標影像的分辨力與CCD像元分辨力的關系及像質(zhì)進行了研究并獲得如下主要結論。1首先仿真了物像與CCD探測器相對靜止情況下的成像過程，仿真中的目標采用鑒別率板的圖案即黑白相間的條帶。
