Abstract : Frequency agility may be added to fire control radars by replacing the conventional receiver-protector/stationary-filter combination located between the duplexing circulator and the receiver input with a passive high power ferrite limiter and YIG tracking filter combination. The invention is an electronic system that is connected between the duplexing circulator and the radar receiver in fire-control radar systems that substantially stops a cw (or pulsed) microwave frequency radar signal used for active missile guidance from entering the receiver while allowing frequency agility of not only the missile guidance frequency but also the radar search and track frequency.
