Abstract
A promising receive system model working in high frequency and wideband, with large processing gain, is researched. As the crux, an acousto-optic correlator is discussed especially. Analyzing the principle of a bulk wave space integrating A-O correlator/convolver, an experimental signal processor with large Gp using a high frequency wideband A-O device is configured. By this system, operation of correlation/convolution with BPSK modulated by Barker code is completed. The result is in accordance with the theoretic calculation. This model works in 175 MHz center frequency, 120 MHz bandwidth, and 29.4 dB processing gain. The method of detecting the first order diffracted light beam is proved theoretically and experimentally to expend dynamic range.
