TLDR
In this paper, the nature of observability of nonlinear systems encountered in passive target motion analysis (TMA) is examined and the approach proposed is based upon a well-chosen criterion which allows us to answer the major observability questions.Abstract:

Efficient Pseudolinear Estimation for Bearings and Frequencies Target Motion Analysis
TL;DR: Two ways to reduce the inherent bias of the pseudolinear estimate for bearings and frequencies target motion analysis and evaluate its performance with Monte Carlo simulations are proposed with reference to the Cramér-Ran lower bound.

Extraction sur données brutes SONAR et Trajectographie associée
TL;DR: In this paper, the authors present a set of methods for extracting "pistes" from images of gisement-temps extraites in order to evaluate the performance of the extracteurs.

Filter re-start strategy for angle-only tracking of a highly manoeuvrable target considering the target's destination information
TL;DR: This study presents a stochastic filter re-start strategy for tracking a target which can abruptly change its velocity in any 3D directions and assumes that the target's destination information is known a priori.
Proceedings ArticleDOI
A Cramer-Rao Lower Bound for the Estimation of Bias with a Single Bearing-Only Sensor
TL;DR: It is shown that highly accurate estimates of bias can be produced using a single sensor, even if the kinematic state estimate of the target is poor, and a Cramer-Rao lower bound on the bias estimation variance is formed.
Improved Filtering And Estimation Methods For Aerospace Problems
TL;DR: This chapter discusses the main themes of the book and some of the strategies used to develop and promote awareness of these themes and their applications in the field of education.

Nonlinear controllability and observability
R. Hermann,Arthur J. Krener +1 more
TL;DR: The properties of controllability, observability, and the theory of minimal realization for linear systems are well-understood and have been very useful in analyzing such systems as discussed by the authors.

Fundamental properties and performance of conventional bearings-only target motion analysis
S. Nardone,A. Lindgren,Kai Gong +2 more
TL;DR: In this paper, the problem of estimating the position and velocity of an object from noise corrupted bearing measurements obtained by a single moving observation platform is considered and a maximum likelihood estimate (MLE) of the target motion analysis solution is developed and its performance analyzed.
Journal ArticleDOI
Observability Criteria for Bearings-Only Target Motion Analysis
TL;DR: In this paper, the observability requirements for bearings-only target motion analysis (TMA) were rigorously established by solving a third-order nonlinear differential equation, and closed form expressions were developed and subsequently used to specify necessary and sufficient conditions on own-ship motion that insure a uniquetracking solution.

Track formation with bearing and frequency measurements in clutter
C. Jauffret,Yaakov Bar-Shalom +1 more
TL;DR: Target motion analysis from a narrowband passive sonar that yields bearing and frequency measurements in the presence of false detections (clutter) in a low-SNR (low signal-to-noise ratio) environment is discussed.
Journal ArticleDOI
Nth-order dynamics target observability from angle measurements
TL;DR: In this paper, necessary and sufficient conditions for the observability of the target's Nth-order dynamics, given direction measurements, were presented, and the derivations are extremely simple and do not require the examination of an observability matrix or nonlinear differential equations.
