FOPEN SAR Enhancements

"Integrated Sensors, Incorporated (ISI) proposes to continue developing a novel Synthetic Aperture Motion Indicator (SAMI) system with foliage penetration (FOPEN) capability. This system will enhance current physical-aperture MTI capability in two ways: 1.)By detecting much slower targets and 2.) By producing SAR images of moving targets.This will lead to significant operational enhancements: The detection of slower moving targets substantially facilitate continuous tracking during a target's "go-stop-go" maneuver. Additionally, the imaging of moving targets will provide a tightly coupledtracking and target ID capability.Phase I clearly demonstrates the capability of this system to detect very slow moving targets (1 meter/sec), while canceling nonmoving targets and ground clutter. During Phase II, ISI will develop a SAMI sensor model to extend the domain of measurableDoppler and quantify the value-added using ISI's MOP/E (Measure of Performance/Effectiveness) tool. The improved tracking performance will lead directly to a target motion compensation procedure capable of focusing a SAR imager on a moving target. Thisallows for the extraction of more precise features from moving targets and there, an enhanced target ID capability.Phase III will extend these capabilities to space-based and bistatic scenarios."
