A simple surface estimation algorithm for UWB pulse radars based on trilateration

Abstract

A simple 3D surface estimation algorithm for ultra-wideband (UWB) pulse radars is presented. This algorithm based on trilateration is easy to implement and needs no preprocessing of measurement data. Mathematical derivations of the formulas for both monostatic and bistatic radar imaging setups are derived. The performance of the proposed algorithm is verified in 3D surface measurements, and a good agreement with well-established methods is shown.
