摘要: 通过对声光信道化接收机基本原理的分析,讨论了积分时间与接收机信噪比改善的关系.建立了声光信道化接收机的数学模型,并在此基础上,对接收机的几个重要指标:信道选择性,带外抑制,动态范围和信噪比进行了分析,完成了声光信道化接收机的设计.最后,给出了自行设计接收机的两个重要指标和光学组件的组成.

Abstract: Through the basic principle analyses of acousto-optic channelized receiver, how to improve the SNR by increasing integrating time is discussed. The mathematical model of acousto-optic channelized receiver is establish to get further analyses. Based on this model, a few important parameter of the receiver are discussed, which are channelized choice,out band control, dynamic and SNR. The design of the acousto-optic channelized receiver is realized. At the end, the two important parameters and the optic system of the acousto-optic channelized receiver which is designed by ourself in our laboratory are presented. The two important parameters are: the frequency of the acousto-optic channelized receiver=50kHz,the channelized number of the acousto-optic channelized receiver=1000.
