This paper reports the progress on the development of an interferometric acousto-optic receiver. The receiver is designed to receive radio frequency (RF) signals as input and generate digital words as output which includes frequency, pulse amplitude, pulse width and time of arrival (TOA). The system consists of the following basic building blocks: the optical bench, the RF reference, the IF portion and the digital encoder. This paper presents alternative designs and corresponding receiver performance. This paper also describes some of the problems and suggests possible solutions to improve the performance.
