  1. Backed up by the soplat theory based on particle kinematics, the second chapter of this paper presents with analysis and simulation of several single observer passive measurement models, which uses such relative movement parameters as bearings changing rates and centrifugal acceleration information on the basis of bearings measurements. in the third chapter, the observability of location respectively using bearings and its changing rates information and centrifugal acceleration information is analyzed, and its observable condition is got. the fourth chapter puts forward the modified covariance extended kalman filtering ( mvekf ) against the defect of traditional extended kalman filtering ( ekf ), whose performance is simultaneously compared in the chapter with the performance of ususal tracking algorithm such as ekf, mgekf, iekf by computer simulation

    在近年來提出的基於質點運動學原理的單站無源定位理論基礎上,本文第二章提出了幾種在角度測量的基礎上增加角度變化及相對運動的離心加度等運動學參數的單站無源測量模型,並對它們進行了分析和模擬;第三章分別對利用角度及其變化信息定位和利用離心加度信息定位的可觀測性進行分析並得到了相應的可觀測條件;第四章針對傳統擴展卡爾曼( ekf )方法的缺點,提出了一種修正協方差的擴展卡爾曼濾波( mvefk )方法,並將其和ekf 、 mgekf 、 iekf等常用的單站無源定位濾波方法進行了性能模擬比較;第五章通過引入機動目標方法和模型,提出了利用角度及其變化對機動輻射源的多級噪聲自適應方法和imm方法;第六章主要對角度變化和離心加度參數的獲取技術進行了研究,提出了幾種高精度測量脈沖序列多普勒頻變化的方法。
  2. 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 )的特點及其回波信號中度、加度等特徵,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,並由此估算目標加度來判斷目標性質,該方法不僅可以在上arm后採用,而且適用於搜索掃描時使用,模擬結果表明該方法具有解析度高,對脈沖重復頻( 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 。
