Acousto-optic spectrum analyzers (AOSAs) provide a convenient means of separating wide bandwidth signals into their frequency components. The two commonly implemented AOSA receivers are fast frequency channelizers and integrating spectral radiometers. By modifying the input signal and by providing additional digital post-processing, the AOSA can also perform radiometry, signal autocorrelation, and cross-correlation. The latter function allows a matched filter receiver to be implemented for signals that have time durations much longer than the signal processor. The resulting signal-to-noise (SNR) improvements from the receiver are consistent with the time-bandwidth product of the waveform, rather than the time-bandwidth product of the acousto-optic device. A mathematical foundation of the processor is presented along with specific receiver implementations.
