ABSTRACT:
An airborne weather radar system having a capability of compensating for variable Doppler shift caused by the forward motion of the aircraft and the relative motion of the antenna sweep which includes a local oscillator having a single low phase noise crystal which is operated in its fundamental mode at a predetermined frequency for increasing the pullability away from the tuned frequency of the local oscillator.
