摘　　要：2CPFSK、BPSK是无人机无线电数据链遥测和遥控系统中的两种主要调制方式。文中设计了一种基于DDS芯片AD9854实现2CPFSK和BPSK数字调制的方案,并给出了电路设计原理与硬件实现方法。该设计实现了无人机无线电测控系统中频的数字化和模块化,提高了遥测、遥控信道的传输能力。通过无人机飞行应用表明,基于芯片AD9854设计的数字调制器性能稳定,实现了遥控扩频数据和遥测复接数据的高速传输。2CPFSK and BPSK are two main ways of modulation in UAV radio data link telemetry and telecontrol system. It introduces a method to complete achieve 2CPFSK and BPSK digital modulation option based on DDS chip AD9854, and gives the principle of circuit design and methods of hardware implementation. The design accomplished digitization and modularization of the UAV radio IF of telemetry and teleeontrol system, improved the telemetry and telecontrol channel transmission capacity. Through the UAV flying application shows that the performance of digital modulator based on AD9854 chip is stable, it implements the high-speed transmission of telecontrol spread spectrum data and telemetry data multiplexer.
