跟蹤導頻信號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 。The key is that the head - end emits the guide m sequence, which is non - correlative with any users " address code. the phase of all users address code and the head - end address code are combined with the guide m sequence. every user address code phase can attain after the guide m sequence phase is searched and tracked
論文所提出的方案是通過前端發射固定的導頻信號,並且在前端和用戶端都把用戶地址碼相位捆綁在導頻相位上,使得用戶在同步捕獲和跟蹤導頻相位后,間接得到用戶的地址碼相位。分享友人
