The performance of Moving Target Indication (MTI) algorithms is an important area of research formaritime surveillance. This paper presents a sea-clutter simulator that incorporates models for the first and second order statistics including the the Doppler spectrum of the sea as measured by the DSTO Ingara airborne radar. By synthesising a number of channels, the sea-clutter model can then be combined with moving targets, thereby allowing modelling of MTI algorithms. For this work, along track interferometry is used to detect simulated moving targets with different polarisations and varying strength sea-clutter. Detection performance is measured using a non-parametric constant false alarm rate detector.
