Pulse compression degradation due to open loop adaptive cancellation. Part 2

An exact expression for the perturbed sidelobe level of a compressed pulse that has been preprocessed through an adaptive canceller has been derived in Part 1. This exact expression requires computer assistance to be evaluated. This report derives a rule of thumb expression that is a good approximation for the canceller noise power level that is induced by having a desired signal present in the canceller weight calculation. An expression for the number of independent samples necessary to equalize the signal-induced power with the quiescent interference level is derived.
