The principle of construction of the digital reverse sum-difference monopulse Doppler direction finder with the orthogonal frequency division sum and difference channels. It is shown that this principle of construction in receive mode to compensate for interference from the direction of the principal maximum pattern without distortion of information about angular mismatch targets laid down in the probing signal by the simultaneous emission of the sum and difference channels. The dependence of the phase error measurement of angular misalignments on the difference between the sum and difference frequencies of channels.
