Abstract
An MTI radar system having a four pulse canceller where the interpulse periods vary preferably according to a double or triple sawtooth pattern is disclosed. The four pulse canceller is comprised of a two pulse canceller cascaded with a three pulse canceller. The three pulse canceller is arranged to accomplish summations of three weighted pulses in two operations, one involving fixed binomial weights (1, -2, 1) and the other variable components (a', b', c'). The interpulse period choices and sequence of use permit the variable weights to be defined by polarity and binary fractions implemented by the use of controllable scalers and polarity reversers.
