  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量的基礎上增加角度變化率及相對運動的離心加速度等運動學參數的單站無源量模型,並對它們行了分析和模擬;第三章分別對利用角度及其變化率信息定位和利用離心加速度信息定位的可觀行分析並得到了相應的可觀條件;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行了性能模擬比較;第五章通過引機動目標跟蹤方法和模型,提出了利用角度及其變化率對機動輻射源跟蹤的多級噪聲自適應方法和imm方法;第六章主要對角度變化率和離心加速度參數的獲取技術行了研究,提出了幾種高量脈沖序列多普勒頻率變化率的方法。
