| 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. |
