Abstract

Current monostatic radar systems suffer fine tracking and discrimination performance degradation when encountering mainlobe jammers deployed within a reentry complex. As a result our forces may be vulnerable to attack. During Phase I, we have developed distributed aperture techniques for mitigating mainlobe jammers which are ready for evaluation in an operational system context. To accomplish this, the algorithms will be perfected to operate reliably in a comprehensive system simulation environment. The result will be a set of software processing modules with interfaces derived from a radar open systems architecture. The interface compliance will be assured by the use of an interface working group. The performance improvements from distributed aperture operation compared to monostatic radar operation will be predicted. Coherent distributed aperture jammer mitigation performance will be demonstrated initially using Applied Radar X-Band Interferometric Radar hardware. Operational performance improvement will be evaluated using engagement simulations employing realistic fleet mission scenarios. These demonstrations will be conducted in established combat system test facilities operated by our transition partner. The result is a spiral integration of improved radar performance applicable to both sea and land-based radar system operation.
