Abstract

A general-purpose space, time and frequency-multiplexed acoustooptic correlator for the synchronization and demodulation of two diverse signals is described. The system achieves an infinite range delay search and complex correlations with full processing gain using multiple m mini-correlations". Signals considered include general I and Q waveforms, MSK (minimum shift keying) and PN encoded data, plus frequency hopped data. The resultant processor achieves the necessary synchronization and demodulation requirements for diverse waveforms (with electronic control of the reference signals provided). The case studies include an identification and a communication application. Novel properties of the processor are its complex-correlation and frequency-selectivity. These attributes are described and applications for them discussed.
