Abstract :
The letter describes the incorporation of amplitude weighting into the response characteristics of a reflective-array compressor. The reflective-array grooves, formed by ion etching, have nonuniform depth, thereby achieving a nonuniform amplitude response. The resulting sidelobe reduction is then evaluated, and the advantages of this weighting method over external and other internal weighting methods are discussed.
