An acousto-optic (AO) range-Doppler processor is interfaced to an advanced ground-based radar system developed by the U.S. Army Missile Command (MICOM). Demonstration of this optical processor in the MICOM radar is the primary objective of this program, part of the DARPA-sponsored Transition of Optical Processors into Systems (TOPS) program. This paper reviews the MICOM radar system, describes the design of the AO range-Doppler processor, and details the digital electronic interfaces required to achieve real-time operation in the MICOM radar. Experimental results for the AO processor are also provided.
A wideband signal processor based on a common module concept is presented that has applications to both radar and signal-intercept applications. This processor is suitable for the coherent pulse compression of wideband radar signals, the intercept/characterization of spread-spectrum radar and communication signals, and the generation of the radar ambiguity function. This paper describes the theory, operation, and application of the processor, which is composed of several modules, including a 1-GHz-bandwidth wideband correlator module, a 200-MHz four-product correlator module, a radio frequency receiver and waveform/transmitter module, and a digital processing and operator interface module for use in field demonstrations.
