摘　　要：由于中小型弹药类飞行器内部的有效使用空间通常比较狭小,而遥测系统作为飞行器研制阶段重要的信号测量系统,也就必须本着体积尽可能小,重量尽可能轻、功耗尽可能低、各平台遥测系统尽可能通用的设计理念。正是基于这种设计理念,论文采用捷变频收发器AD9364来进行遥测信号的无线传输。通过把采集的遥测信号组帧并进行PCM-FM调制,将调制后的信号传给AD9364直接上变频,通过飞行器上携带的天线向地面设备发射。通过实际的应用发现,该设计相对于传统的遥测系统,具有集成度高、体积较小、功耗较低、兼容性强等优势。Because of the effective using space of a small ammunition inside the vehicle is usually small,and telemetry system as aircraft development stage important signal measuring system,must also be the purpose of volume as small as possible,and weigh as much as light and power consumption as low as possible,the platform telemetry system as much as possible concept of universal design. It is based on this design conception,this paper uses frequency hopping transceiver AD9364 to carry out the wireless transmission of telemetry signal. Through the acquisition of the telemetry signal group frame and PCM-FM modulation,the modulated signal transmitted to the AD9364 directly on the frequency conversion,through the aircraft carried on the antenna to the ground equipment. Through practical application,it is found that this design has the advantages of high integration,small volume,low power consumption,strong compatibility and other advantages compared with the traditional telemetry system.
