Abstract
An intermediate frequency sidelobe canceller of the kind including a cancellation loop, with provision added for programming the correlation signal weights which control operation of the loop. This capability is provided by switch means interposed in the cancellation loop within the correlation signal branch thereof and selectively operable to break the loop and then either to substitute for the normally weighted correlation signal to the canceller another signal of different weighting, such as an externally supplied signal, or to retain or 'hold' the current value of the correlation signal. Such substitution affords improved canceller operation and adaptability to otherwise difficult operating conditions such as strong clutter and transmitted pulse interference.
