摘　　要：目前传统的接收设备大多采用分离元件设计,系统结构固定、功能单一、体积较大,难以满足弹载环境下对体积的约束和未来不断变化的作战需求。基于此,提出采用中频数字解调实现弹载指令接收的思路,由此展开对数字解调中采样率选择、数字下变频、同步等关键技术及其算法的研究;并在Simulink平台下建立中频数字解调系统的仿真模型,仿真结果表明所提出的技术适用于现有的工程技术研究。At present, owing to the adoption of discrete component design, most traditional receivers have the problems such as regular system structure, single function and large size, which are difficult to satisfy the restriction of volume under the on-board environment and meet the demand of variation of warfare condition. Based on those,we proposed the idea of the digitization demodulation in order to realize on-board instruction receiving. Therefor the reserch of key technologies and algorithm involved in the sampling rate choice,digital down conversion, synchronization have been made. And also we finished the IF digitization demodulation system＇s model under Simulink, simulation results have shown that the technology proposed is suitable for the existing engineering technology research.
