A signal processing method is presented for correcting imbalances in the phase detection channels of a coherent, wideband radar. The technique, an expansion of an earlier method, derives phase and gain corrections using an external point target illuminated by a wideband waveform. The technique does not depend upon the target or the phase and gain flatness of the radar waveform. Errors remaining after application of this technique depend on the signal to noise ratio and the correlation of the sampling with the radar waveform.
