520 |a"An optoelectronic processor was built at DREO for the detection and processing, of spread spectrum radar and communication signals in the presence of noise and interfering signals. The design and performance of the processor, a Time-Integrating Correlator (TIC), are presented. A general description of the TIC, its operation, components, and subsystems is included. The signal processing and the data collection procedure are also described. The digital controller, the packaging of the system, and the effects of temperature changes on the stability of the TIC are presented. Experimental measurements of the performance of the TIC were performed with binary phase shift keyed input signals with chip rates up to 20 MHz, and results are included. The TIC has a 30 MHz bandwidth and can reliably detect correlation peaks on a time difference of arrival window of 90 μs. The dynamic range of the prototype is 60 dB, and it can produce detectable correlation peaks in additive white Gaussian noise for input signals having a signal-to-noise ratio of -35 dB while using a processing gain of 40 dB. The performance of the TIC, for that particular set of parameters, is thus within 5 dB of the theoretical limit"--Abstract, page iii.
