  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率及相對運動的離心加速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率信息定位和利用離心加速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 )法的缺點,提出了一種修正的擴展卡爾曼濾波( mvefk )法,並將其和ekf 、 mgekf 、 iekf等常用的單站無源定位濾波法進行了性能模擬比較;第五章通過引入雷達機動目標跟蹤法和模型,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適應法和imm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進行了研究,提出了幾種高精度測量脈沖多普勒頻率變化率的法。
  2. It comes up with a new notion, d - solution, which is applied to the distance estimation, by virtue of hilbert space ; furthermore, the dissertation has gained a necessary condition which is identity of minimum mean - square value in linear function classes, so that d - solution extends minimum mean - square value within the domain of nonlinear function equation or equation system ; and, the dissertation studies in detail the classical moment estimation and maximal likelihood estimation on the parameters of ar ( p ), a series of theorems in the estimation section shows the moment estimators are consistent on the ground of large samples jikewise, those distribution functions of the estimated parameters accord to maximum likelihood estimation converge gauss distribution if the white noise is gaussan

    首先,藉助hilbert空間理論,提出了距離估計的d -解,給出了d -解的必要條件,這個條件在線性函數類里即是極小二乘估計法, d -解的必要條件滿足的程實質上將極小二乘估計法推廣到多函數及非線性函數類。再而,詳細地研究了多元弱平穩回歸模型ar ( p )的參數經典的矩的替代估計和極大似然估計,獲得矩的替代估計的一致性的結果。對基於gauss白噪聲假設多元弱平穩回歸模型的均值、白噪聲的陣的極大似然估計都有依分佈收斂到多元正態分佈的統計性質。
