  3. The second part brings forward a new ar - model - based arm detection method based on features of arm and characteristics of velocity and acceleration of the radar echoes. by establishing two - order ar models, this new detection method computes the poles of models representing different targets, thus estimates the acceleration of the targets so as to determine the nature of the targets. furthermore, this method can not only be applied when the arm is being tracked by radar, but also be put into use in radar ’ s seeking and scanning times

    第二部分則是根據反輻射導彈（ arm ）的特點及其雷達回波信號中速度、加速度等特徵，提出了一種新的基於ar模型的arm檢測演算法，該方法通過建立二階ar模型、估計代表不同目標的模型極點，並由此估算目標加速度來判斷目標性質，該方法不僅可以在雷達已跟蹤上arm后採用，而且適用於雷達搜索掃描時使用，模擬結果表明該方法具有解析度高，對雷達脈沖重復頻率（ pulserepetitionfrequency ， prf ）及積累脈沖數要求不高的特點，在低的prf及少的積累脈沖下，利用該方法仍可有效地識別檢測arm 。
