A target tracking radar receiver for use in a semiactive tracking system wherein elevation angle data, azimuth angle data and Doppler frequency shift data are processed in a manner which enables narrow band filtering of target angle tracking data in the first intermediate frequency stage. The receiver is arranged to track, simultaneously, variations of target Doppler frequency and of transmitter frequency to permit the desired early narrow band filtering of the received angle data.
In a semiactive guidance and control system whereby a missile, in accordance with radar signals received directly from a radar transmitter and in accordance with echo signals reflected from a target, is directed to an intercept with such target, a receiver comprising: (a) front antenna means and rear antenna means mounted in the missile for receiving, respectively, echo signals from the target and radar signals from the radar transmitter; (b) a front heterodyne receiver channel means, including a first mixer connected to the front antenna means, for prod...
