摘　　要：为监测无人机发动机在空中的工作状态,需要通过无线信道把发动机缸体温度、油压、油耗以及发动机声音等参数传回地面的监测站,因此有必要研制一种低成本、小型化的下行传输链路;介绍了基于ADF7020-1单片收发芯的发射机设计方法,通过对间接锁相调频相位传输模型的理论分析,建立了间接调频发射机的设计方案;经过搭载无人机进行动态飞行验证表明,设计的发射机完全能准确地把发动机各种参数和声音传输到地面监测站,可推广应用于其它数据传输系统中。For monitoring the status of engine of UAV, the parameters which are the temperature of cylinders, oil pressure, oil consumption and voice of engine must be sent to the ground station by wireless link. Therefore, a downlink which is low cost and miniaturization need to be designed. Based on ADF7020 - 1 chip, a designed scheme of transmitter will be proposed. By analyzing indirect lock phase frequency modulation transmission model, the designed scheme of indirect frequency modulation transmitter can be set up. The flying experiments of UAV show that the designed transmitter can send the parameters of engine and voice to the ground station exactly and can be applied on the real data transmission system.
