Abstract
The Acousto-Optic Spectrum Analyzer (AOSA) has undergone a theoretical design review and a basic parameter trade-off analysis has been made. The main conclusion is that for the given scenario of a 55 dB dynamic range and for a 1 sec temporal resolution, a 3.9 MHz resolution is a reasonable compromise with respect to current technology. Other configurations are suggested as well. Noise Testing of the Signal Detection Processor (SDP) algorithm was performed. Additive white Gaussian noise was introduced to pure data. As expected, the trade-off was between algorithm sensitivity and false alarms. No additional algorithm improvements could be made. The algorithm was observed to be robust provided the noise floor was set at a proper level.
