High Frequency Resolution Acousto Optic Channelized Receiver

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.
