This paper investigates the direct position determination (DPD) problem from passive measurements made with a moving antenna array in the case of a time-varying number of emitting sources. We derive the Cramér-Rao bound (CRB) for the estimation problem and find an approximation that is applicable for a large number of observations. We use different DPD approaches to solve the estimation problem. Therein,...
Emitter geolocation under local scattering environment is explored. We derive an analytic model for the received signal where the local scattering environment is modeled as a stochastic process using the Gaussian Angle of Arrival (GAA) model. For the signal model we provide both optimal and sub-optimal, computationally-simpler, 1-step (direct) emitter geolocation algorithms. The proposed algorithms...
