ABSTRACT:
A device for automatic correction of differential and deterministic errors in a radar receiver, preferably a monopulse radar receiver, which comprises a closed loop feedback system in which raw Off-Boresight Angle (OBA) data as well as current azimuth data are accumulated, averaged and linearized through linear aggression techniques. This linearized data is combined with data relating to pre-calibrated known antenna parameters. This combined data is fed back and combined with the raw OBA signal to produce a correction OBA signal. The corrected OBA signal is algebraically summed with the current known azimuth data produced by the radar receiver to produce a highly reliable error corrected instantaneous OBA value.
