Abstract
Disclosed is a magnetron powered selectable pulsewidth radar system having minimum receiver bandwidth for each pulsewidth and automatic centering of the intermediate frequency at the true center of the input filter pass band. A frequency discriminator adjusts the local oscillator frequency after each transmitted pulse to cause the intermediate frequency on the return of that pulse to equal an internal adjustable frequency reference. The filtered IF noise signal between received pulses is compared to the internal reference by the frequency discriminator and its output is used to adjust the reference to equal the center frequency of the actual receiver input pass band.
