  1. Through analyzing the spinning echo, the arithmetic of " estimation of signal with polynomial phase " is adopted to estimate parameter of echo ' s phase. then the influence of high step phase pro duced by spin is removed. the one - dimension range - profile can be renewed by this arithmetic and the good effect is showed by the result of simulation in chapter v, the main works of this dissertation are summarized and the future researched areas are pointed out

    通過對自旋目標回波的分析,本章採用了「多項式相位信號系數估計」演算法對回波相位進行參數估計,可以去掉旋轉產生的相位高次項影響,從而恢復給出目標的一維距離像,模擬實驗表明本演算法取得了好的效果。
