Side-lobe canceller response for pulse interference

The side-lobe canceller response for the pulse train interference is discussed. This type of the interference is caused by jammings or the radiation from other radar. The differential equation which governs the control weight of the canceller is solved and the solution is related to several operational parameters of the canceller such as the loop filter time constant, the loop gain, the interference power, the repetition period, the duty factor of the pulse and so on. Based on the results obtained here, the optimum loop gain and time constant can be selected to satisfy the given conditions for cancellation.
