A Refined Maximum Likelihood Method for Tracking Low-Altitude Targets Over the Sea: Results of Simulation and Experiments
Abstract
Accurate radar tracking of targets flying at low altitudes above a smooth surface is difficult because of the surface reflection. We propose a solution based on deterministic physical modelling of the specular multipath and the maximum likelihood method. This paper describes the techniques and the results of the performance studies. We derive the Cramer-Rao bound and show the benefit of using the refined propagation model. Monte-Carlo simulations are employed to compare the performance with the Cramer-Rao bound and demonstrate threshold effects on target height estimation. Finally we present the results obtained with two X-band radar experimental systems.
