This paper reports the final experimental results and conclusions on the performance of an interferometric acousto-optic receiver (IAOR). The receiver is designed to acousto-optically channelize a 1 GHz RF bandwidth spectrum into 128 frequency bins, and generate digital frequency, pulse amplitude, pulse width and TOA words. Experimental results show that the predicted performance improvement over the power acousto-optic receiver (PAOR) is significantly below expectation. Key factors contributing to performance degradation are discussed along with supporting experimental data. Recommendations for further acousto-optic receiver work are presented.
