High Range Resolution Radar Cross-Section Profiles: A Preliminary Analysis

Abstract

The following provides a brief and informal account of an analysis technique used by the Electronic Warfare Division (EWD) to produce high range resolution radar cross-section (RCS) profiles of maritime targets. We begin by giving a simple theoretical discussion of the basic principle behind the technique employed, and then move on to describe the computer program used to carry out the first stage of the RCS analysis and make comparison with other work. High range resolution RCS profiles, were derived for a maritime target with the use of a coherent radar system developed by the Microwave Radar Division (MRD). Synthetic range profiles were obtained for the ship by exploiting the reciprocal relationship that exists, in the context of the present work, between range and frequency and by employing a fast Fourier transform (FFT) algorithm to evaluate the inverse discrete Fourier transform (IDFT). The technique is referred to in the literature as stepped frequency imaging. Keywords: Active and passive radar detection and equipment, Radar cross section, Australia, EWD, RCS.
