Synthetic Aperture Radar (SAR) Coherent Change Detection (CDD)
Abstract
The Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) Initiative encompasses four phases to develop deployable systems capable of SAR with real time CCD processing to provide over the horizon alerts for terrain changes above a given threshold. The focus is on increasing the situational awareness of small dispersed units operating in large areas. Phase One validated the performance of existing lightweight SAR systems using CCD for detecting a variety of human activities through rigorous testing. Phase Two demonstrated near real-time CCD on a manned SAR-equipped platform used to determine functional requirements and developed a system concept of operations (CONOPS). Phase Three has developed the engineering enhancements necessary to integrate a real time SAR CCD capability on a small UAV. All necessary software was developed during this phase. Phase Four (FY 2010) will extend the capability to an affordable small unmanned aircraft with a miniaturized SAR system. Phase Four will also decrease procurement costs of a small SAR with a real time CCD capability to a cost goal of $500 thousand per sensor package. This compares to a current cost of approximately $1.2 million for a spot SAR system.
