Monopulse processing systems

摘要: A secondary surveillance radar system in which monopulse processing (100) is used to obtain angle estimation of azimuth bearing, the improvement residing a precision method, involving qualifier signal (120), for identifying maximum unambiguous off-boresight (OBA), while ensuring reduced sensitivity Omni channel variations; developed from coherently combining IF limited signals (110) derived Sum + jDelta and Delta jSum (72, 74) such that two amplitude varying are created, bearing direct relationship Difference antenna pattern ratios being independent power.
