Based on the multiplicative speckle model, a new filtering algorithm based on wavelet transform was developed. first, the multiplicative speckle noise was changed by logarithmic transform into additive noise, which simplified the subsequent speckle suppression. the speckle suppression was carried out in the process of wavelet transform of the logarithmic transformed image
針對斑點噪聲的乘性模型特點，構造了一種基於小波分析的濾波器：對sar圖像進行對數變換，利用小波變換對對數圖像進行濾波處理，再通過指數變換得到去噪圖像。
