Abstract
In order to increase the available signal processing bandwidth of an acousto-optic coherent channelizer, the optical beam spot-shaping and projection components of the channelizer are configured to project M reference beam spots upon each photodetector of the channelizer's photodetector array. The parameters of the reference Bragg cell, reference signal R(t), and Fourier optics components are such that they project M reference beam spots upon each photodetector of the channelizer's photodetector array, where M is the desired system bandwidth multiplication factor. No change to the configuration of the photodetector array or its associated post-detection signal processing electronics is required.
