Differential received signal strength (DRSS) provides a practical means of localisation for wireless sensor networks. Closed-form location estimators based on a linearised propagation path loss model are computationally efficient and hence suitable for wireless sensor nodes. However, most existing s…
A two-step pseudolinear Kalman filter (2S-PLKF) was previously proposed for angle-of-arrival (AOA) target tracking in three-dimensional space drawing on the pseudolinear rearrangement of nonlinear azimuth and elevation angle measurement equations. Despite enjoying low computational complexity, this…
This paper develops a new computationally efficient bias reduction method for the well-known algebraic closed-form solution for time-difference-of-arrival (TDOA) localization developed by Chan and Ho. The noise correlation between the regressor and regressand in the formulation of the linearized lea…
In Doppler-bearing source localization, pseudolinear estimators are appealing alternatives to the divergence-prone and computationally-demanding iterative maximum likelihood estimator. Among the existing pseudolinear estimators, the weighted instrumental variable estimator (WIVE) is the most attract…
Closed-form pseudolinear estimators are computationally attractive alternatives to iterative nonlinear techniques. For time-of-arrival (TOA) based localization, several pseudolinear estimators have been proposed such as the least squares calibration (LSC) estimator, the linear least squares (LLS) es…
This paper presents a new algebraic solution for the Doppler positioning problem where the position of a stationary emitter is estimated from Doppler frequency measurements collected by a single low-earth-orbit (LEO) satellite. The proposed algebraic solution can be used for effective initialization…
This paper derives the optimal angular geometry for elliptic time-of-arrival localization by a multistatic radar consisting of multiple independent bistatic channels. The optimal geometry analysis is conducted based on minimization of the area of the estimation confidence region which is equivalent…
