介绍了一种高动态范围声光接收机，这种接收机具备实现宽带射频信号幅度，频率和相位的信道化探测能力。该接收机在０．６３２８μｍ激光器的工作条件下（１．０ｍＷ），声光布拉格盒在５０ｍＷ射频信号驱动下，在１４０ＭＨｚ的中心频率上，２０ＭＨｚ带宽内，对单频信号动态范围测量结果的超过５５ｄＢ；当两个等幅、频率不同的射频信号同时加到布拉格元件上，其动态范围测量的结果超过５０ｄＢ。频率分辨率可达到１０ｋＨｚ。 A high dynamic range acousto-optic receiver is introduced, which has the channelization detection capability of realizing the amplitude, frequency and phase of broadband radio frequency signal. The receiver in the 0.6328μm laser working conditions (1.0mW), acousto-optic Bragg box 50mW RF signal driven at a center frequency of 140MHz, 20MHz bandwidth, the single-frequency signal dynamic range measurement results exceeded 55dB; When the two equal amplitude and frequency of the RF signal applied to the same time Bragg components, the dynamic range of the measurement results of more than 50dB. Frequency resolution up to 10kHz.
