Abstract
This paper presents a method for determining the spatial coordinates of a moving radiation source on the basis of a two-position system from measurements of one bearing and relative energy measurements of the received signal taking into account the effect of its reflection from the Earth surface.пThe passive location problem is solved for low elevation angles taking into account the curvature of the Earth and using a polynomial model of source motion. An algorithm is developed for the parametric identification of this model based on a sample of measurements of increasing size in a regularized formulation, and the accuracy characteristics of the method are analyzed.
