  1. After the compensation based on the rule of the minimum entropy, the resolution of the cross - range image is lower as the large size and non - uniform rotation, which cause the image to be not right at all sometimes. in order to eliminate effect of the non - stationary rotation, the first order approximation and relax algorithm are adopted to search the initial frequency, amplitude, frequency modulation rate and obtain the dynamic image of the target at any time

    分析了低分辯雷達的成像演算法,建立在最小熵補償基礎上的演算法得到的橫向像的解析度仍然比較低,尤其對大的目標和機動目標,為此我們採取了一階近似的relax演算法搜索目標的初始頻率、幅度、解調率從而獲得目標的動態一維像,模擬數據和試驗結果證明該方法是有效的。
