ABSTRACT:
In a radar system employing an array antenna and microwave circuitry coupled thereto for developing sum and difference signals, a correction circuit utilizes the sum and difference signals for providing increased accuracy to elevation and azimuthal angle measurements of wide bandwidth radar signals. A correction is applied to the difference signal by subtracting therefrom a weighted time derivative of the sum channel, the weighting being proportional to the boresight error slope and the sines of the elevation and azimuth angles.
