摘要： A method and correction circuit is described incorporating a monopulse receiver, injecting a first signal of known amplitude and arbitrary phase and a second 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 ouptut signals of the channel to provide a corrected output. 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.

摘要： A plurality of amplifier channels, wherein each channel is automatically gain controlled by a gain control signal and wherein the gain of each channel is a known function of a plurality of constants of corresponding to each amplifier and of the gain control signal, can be calibrated by the following method. The method comprising the steps of measuring each output of each amplifier at a corresponding plurality of gain control values and at a corresponding input to each amplifier. The number of the plurality of the constants equals the number of the plurality of the gain control values. The method continues by computing the gain of each amplifier at the step of measuring. The constants corresponding to each amplifier are then computed according to the function and computed gain. A corresponding changed gain control signal is applied to each amplifier according to the function to set the corresponding gain of each amplifier to a corresponding predetermined calibrated value. By virtue of this methodology, the gain of each channel of a multiple channel amplifier can be not only calibrated to equal a preset value, but the gains of each of the channels can be matched, all without the use of any other additional test equipment.

摘要： The invention comprises a system for controlling and normalizing the gain of the difference I.f. I.F. to the gain of the sum I.F. amplifier in a monopulse radar. A pulsed, I.F., pilot signal is applied to both the sum and difference I.F. amplifiers at predetermined intervals chosen so that the pilot signal does not interfere with the echo return signal. The outputs from these I.F. amplifiers are gated at the predetermined intervals coinciding with the application of the I.F. pilot signal. These gated, sum-and difference-amplifier, pilot signals are envelopedetected and then applied to a differential amplifier. This differential amplifier generates a signal representative of the difference between the sum and difference amplifier pilot signals and applies this signal to the difference, I.F. amplifier to control its gain. The sum I.F. amplifier has a conventional A.G.C. system for gain control. The control signal generated by this conventional A.G.C. system is also applied to a circuit for controlling the signal level of the I.F. pilot signal so it is inversely proportional to the signal gain level of the sum I.F. amplifier. This controlled I.F. pilot signal is then applied to the sum and difference I.F. amplifiers (as stated above) via a hybrid network and directional couplers, at a time chosen so that it does not interfere with the predicted echo-return.
