A Novel Noncoherent Monopulse Processing Scheme and Its Channels Imbalance Analysis

The noncoherent processing can alleviate the effect of phase imbalances in receiver channels of monopulse radar. In this paper, a novel noncoherent processing scheme, which uses logarithmic amplifiers, is considered and explicit expressions are derived for the indicated angle as a function of various imbalances in the receiver channels. Its performance is then analyzed using shift in null position and deviation in slope of the angle sensitivity curve as criteria. Its performance in some aspect is superior to that of the conventional monopulse processing due to symmetrical channels and wide dynamic range.
