Large time-bandwidth product acoustooptic correlator and its use in a cascade design matched filter.
An acoustooptic correlator was constructed using PbMoO(4) deflectors whose acoustic transit time was 7.5 microsec. This correlator performed successfully at 40 MHz using a 127 bit pseudonoise code. A new matched filter concept is presented which can be realized with similar acoustooptic deflectors and commercially available acoustic delay lines. It utilizes a hybrid combination of digital shift register electronics and acoustooptic techniques to achieve an almost unlimited time-bandwidth product.
