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
Through the analysis of the basic principle of the acousto-optic channelized receiver, the relationship between the integral time and the improvement of the signal-to-noise ratio of the receiver is discussed, and the mathematical model of the acousto-optic channelized receiver is established. Based on this, An important index: channel selectivity, out-of-band rejection, dynamic range and signal-to-noise ratio were analyzed and the design of acousto-optic channelized receiver was completed.Finally, two important indexes of self-designed receivers and optical components The composition
