“…For example, in a case where a location S 1 , obtained by Whistle, is (10,20,30) and the exact sound source S = (8,22,30), |x S1 − x S | = 2m > 1m shows that the result of S ′ is an outlier. Fig.…”

“…It is well understood with light-of-sight (LOS) measurements, and a full quiver of algorithms, such as maximum likelihood (ML) [1][2] [3], least squares (LS) [4], and the Stansfield estimator [1][5], have been developed for different application circumstances. Instead of LOS AoAs, this paper concentrates on localization with non-line-of-sight (NLOS) reflection measurements, where the radiation from a target reaches distributed sensors after a single specular reflection.…”

Bearings-only localization with light-of-sight (LOS) propagation is well understood. This paper concentrates on bearing-only localization with non-line-of-sight (NLOS) measurements, where the target radiation arrives at the sensor after a specular reflection. The wrinkle is that the reflecting surface is circular (inner side of a circle), and is assumed known. Since the target-sensor geometry has multiple configurations, the maximum likelihood (ML) solution may not exist. However, if a concentric opaque circle (such as the earth) exists within the reflecting one, the propagation path is unique; a grid search based ML is available for such a circumstance. Since ML is computationally consuming, two suboptimal algorithms based on small angle approximation are developed. Their performances are numerically compared.

“…Bearing-only tracking (BOT) techniques are applied in various scenarios of target location, and the related theoretical and practical problems have been studied for decades [1][2][3]. The accuracy and efficiency of the target location have witnessed significant improvement in recent years due to the improvement of advanced filtering techniques [4][5][6] and UAV (unmanned aerial vehicle) platform.…”

The optimal maneuver of observer for bearing-only tracking (BOT) in a threat environment is a complex problem which involves nonlinear filtering, threat avoidance, and optimal maneuver strategy. Under comprehensive consideration, the reward function comprised of the lower bound on detFIM and threat cost was established; the finite-horizon MDP principle was applied to obtain the optimal strategy. The quantization method was used to discretize the BOT process and calculate the transition matrix of Markov chain; to achieve quantization in the beginning of each period, CKF was applied to provide the initial state estimate and the corresponding error covariance. The numerical simulations illustrated the applicability and superior performance for static and dynamic target tracking in several scenarios in the threat environment.
