Abstract
THIS PROJECT IS AIMED AT THE DEVELOPMENT OF COHERENT SIDELOBE CANCELLER (CSLC) TECHNOLOGY IN THE HIGHER MICROWAVE REGION FOR APPLICATION TO THE TACTICAL FIGHTER X-BAND RADAR. IT WILL SPECIFICALLY ADDRESS A NUMBER OF DESIGN ISSUES, INCLUDING AUXILIARY ANTENNA DESIGN, CLUTTER/JAMMER INTERACTIONS, BLINKING JAMMERS, SLOW CONVERGENCE OF LMS ALGORITHMS, APPLICATION OF SMI ALGORITHMS, MOTION EFFECTS, RF-TO-DIGITAL CONVERSION ERRORS, ERROR EFFECTS DUE TO MULTIPATH SCATTERING AND POLARIZATION EFFECTS. A KEY FEATURE OF THE PROGRAM IS THE APPLICATION OF SPACE/TIME ADAPTIVITY TO THE CLUTTER/JAMMER INTERACTION PROBLEM. THIS MAY ALSO IMPROVE OVERALL CLUTTER SUPPRESSION PERFORMANCE OF THE RADAR BY ADAPTIVELY CANCELLING SIDELOBE CLUTTER, ALONG WITH SIDELOBE JAMMING, USING A CSLC AUXILIARY ARRAY. ANOTHER FEATURE OF THE PROJECT IS THE USE OF A TIME-SAMPLE COMPUTER MODEL, IMPLEMENTED ON A HIGH SPEED ARRAY PROCESSOR IN A SUN WORKSTATION ENVIRONMENT, WHICH WILL CLOSELY REPRESENT REAL HARDWARE. FINALLY, THE PROJECT WILL DEFINE A PHASE II PROGRAM WHICH WILL DEVELOP AN EXPERIMENTAL X-BAND TEST BED FOR CONDUCTING LABORATORY AND ROOF TOP TESTS.
