高分辨率声光信道化接收机

High Frequency Resolution Acousto Optic Channelized Receiver

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。

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=50?kHz,the channelized number of the acousto optic channelized receiver= 1?000.
