Sidelobe cancellation SLC is a technique employed to reduced the effects of interference entering a radar or communications system via the aerial sidelobes. As its name suggests, the technique involves cancelling the sidelobe through which the umwanted signal is being received. In order to achieve cancellation of a specific sidelobe of an aerial it is necessary to add an antiphase signal of equal level to that received by the sidelobe in question. This cancels the particular sidelobe of concern, but what effect does the addition of this signal have upon the remainder of the aerial pattern and the associated radar or communications system This memorandum reports upon a preliminary investigation conducted into this question from both a theorectical and a practical approach.
