Development of Advanced Radar Technologies for Missile Defense

Integrated Sensors, Incorporated proposes to develop and demonstrate techniques that effect practical, operationally meaningful, simultaneous mainlobe/sidelobe jamming cancellation in solid state, active array radars while preserving target angular accuracies and permit operation in clutter and jamming environments. Two innovative and promising architectures will be examined: (a) an Adaptive Maximum Likelihood Beamspace (AMLB), and (b) a Multi-Band Adaptive Maximum Likelihood Beamspace (MB-AMLB) architecture. The latter architecture is a highly robust concept that optimally exploits information from either multi-band or ultra-wide band (UWB) radar systems. The primary emphasis is: (1) to address phased array radars that do not have access to their subarrays, i.e., only traditional sum, difference, and auxiliary channel availability is assumed, and (2) to design an architecture that will effectively suppress simultaneous sidelobe and mainlobe jamming. Our demonstration plan includes an experimental system including a phased-array radar as part of a comprehensive Phase I and Phase II program, eventually leading to implementation of jamming suppression processors for retrofit into existing Army radars.
