Organic Maritime ISAR Efficacy Via Aroma Data Algorithm
Abstract
Synthetic aperture radar (SAR) is an invaluable part of the overarching information, surveillance, and reconnaissance (ISR) architecture. Traditional SAR elements, particularly aircraft and satellites, are detached from the consumers of SAR imagery. SAR imagery as a product is produced via the relative motion between the radar and the scattering centers of the target of interest. Thus, simulation is conducted to determine whether it is possible to develop a SAR system that can be used for imagery on the consumer level. Arbitrary rigid object motion autofocus (AROMA) simulates the pitch and roll of a surface vessel by way of a physical signal model designed to include both translational and rotational motion. AROMA uses this method to mitigate phase errors induced by target motion and generate images as though the target remained stationary, lending significant utility for maritime target identification. The validity of AROMA as a means of imagery production is evaluated through simulation of a SAR system with AROMA as an image processer, against a target experiencing varying sea state conditions.
