A study of performances of multipath height estimation algorithm for marine target imaging

Abstract

In this paper, a new method is proposed to retrieve target reflectors heights for maritime surveillance applications. Multipath propagation over sea surface is used to retrieve the height information for each target reflectors. Firstly, radar raw data with multipath propagation are simulated. The backscattered electric field from a marine scene is predicted with physical models for the environment and the target. The scene is made of given wind conditions, a linear sea surface and a boat, as a set of point reflectors. Multipath propagation is included with the so-called Four-Path Model. Secondly, height estimation of target reflectors is realized by estimating temporal delays between neighbouring paths of the multipath propagation pattern. Performances of the height estimation algorithm for only one reflector are studied with regards to noise levels.

A Novel Target-Height Estimation Approach Using Radar-Wave Multipath Propagation for Automotive Applications

“…For maritime surveillance applications, simulation results of a study conducted to estimate the height of marine targets were provided in Habonneau et al (2013b, a). The approach consisted of estimating temporal delays between neighboring paths of a multipath propagation pattern over the sea surface to approximate the height of a target reflector.…”
