ELECTRONICALLY SCANNED (E-SCAN) ANTENNA TECHNOLOGY FOR A LIGHTWEIGHT BATTLEFIELD SURVEILLANCE RADAR

THIS PROPOSAL PRESENTS THE PRELIMINARY DESIGN AND ANALYSIS OF A PORTABLE, LOW-POWER, HIGH RELIABILITY BATTLEFIELD SURVEILLANCE RADAR INTENDED TO REPLACE SYSTEMS SUCH AS THE AN/PPS-5 AND AN/PPS-15 SYSTEMS. IT DETAILS THE SYSTEM AND HARDWARE DESIGN TRADEOFFS, AND SHOWS THE RESULTS OF A SYSTEM LEVEL PERFORMANCE ANALYSIS INCLUDING THE MODELLING OF RANDOM AND NON-RANDOM ERRORS. EMPHASIS HAS BEEN PLACED ON DESIGN FOR RELIABILITY AND COST EFFICIENCY. THE PROPOSED SYSTEM TAKES ADVANTAGE OF A UNIQUE MMIC TIME-DELAY PHASER CHIP TO PROVIDE LOW QUIESCENT POWER OPERATION, AND INCORPORATES MICROWAVE PRINTED CIRCUITS WHICH ELIMINATE MANY OF THE LOW-RELIABILITY COMPONENT INTERCONNECTIONS.
