A method and correction circuit is described incorporating a monopulse receiver (30), injecting a first signal of known amplitude and arbitrary phase and a send signal of the same amplitude shifted 90.degree. and measuring the output voltages of the channel and using the measurements to generate four coefficients which may be mathematically applied to the output signals of the channel to provide a corrected output (71, 72, 71', 72'). The invention overcomes the problem of compensating for phase and gain drift in the in-phase and quadrature paths of the sum and difference channels of a monopulse receiver,
