摘要
介绍一种采用双反向通道ＴｅＯ２反常声光器件构成的空间积分声光相关器（ＳＩＡＯＣ）。使用直接探测法对矩形脉冲调制的模拟雷达信号进行了抗干扰实验，当矩形脉冲宽度为１０μｍ时，相关增益可达１６ｄＢ。
A space intergrating acousto-optic correlator(SIAOC) using one extraodinary acousto-optic device with two oppositely directed channels is proposed. Some interferencefree experimental results for analog radar signal (high- frequency signal modulated by rectangular pulses ) through directed detection are given. When the width of the rectangular pulses is 10 μs, the correlative gain is 16 dB.
