Abstract :
In this paper we discuss the frequency-jump burst (FJB) waveform as a candidate for performing joint synthetic aperture radar (SAR) imaging and ground moving target indication (GMTI). We introduce the signal model for simulating SAR data and the method for image formation. The ambiguity function (AF) is used as an analysis tool for determining whether the waveform under investigation has the desired resolution. Image artefacts resulting from target motion are discussed and the degradations are quantified.
