Abstract
An airborne radar warning receiver for track-while-scan radar including a first radar frequency receiver and logic circuitry for determining an increase in pulse rate frequency, second radar frequency receiver connected to a signal filter and an automatic gain control amplifier connected to the receiver and a logic circuitry connected to the amplifier and to the pulse rate frequency logic whereby the ratio is determined between the time from the start of scan until the radar beam illuminates the aircraft and the total scan time, thereby indicating the center of a search scan sector. A third radar frequency receiver connected to a signal filter and a logic circuitry connected to the receiver for indicating when signals are being radiated indicative of the launching of a radar controlled missile.
