An Explicit Bistatic Glint Solution for an Arbitrary Number of Scatterers Using the Phase Gradient Method
Abstract
Given multiple unresolved scatterers in range, Doppler, and angle, estimation techniques that assume that only a single target is present, such as traditional monopulse estimation, are well known to produce biased estimates, particularly in angle. This paper derives the apparent target location and range rate in the presence of multiple scatterers utilizing the phase gradient method. The solution is given in 2D/3D Cartesian coordinates. Additionally, bounds on the maximum and minimum errors are given in 2D for the two-scatterer problem.
