A Comparative Study of Acousto-Optic Time-Integrating Correlators for Adaptive Jamming Cancellation

Abstract

This final report presents a comparative study of the space-integrating and time-integrating configurations of an acousto-optic correlator. Correlation of wide bandwidth time-domain signals is an important consideration for adaptive jamming cancellation. The primary objective of this effort was to systematically evaluate all existing acousto-optic correlator architectures and to determine which would be most suitable for adaptive jamming cancellation applications. An experimental investigation into the effects of vibration on the dual-path time-integrating correlator was also conducted. Results show that at low signal frequencies (i.e. 1MHz) the correlation function fluctuates in an unpredictable manner; however, at high signal frequencies (i.e. 5MHz) the effect of vibration is negligible.
