Design Of RF Channel For UAV Datalink

UAV is small impacted by climatic conditions, available day and night, without personnel loss, risk, low cost, able to enter dangerous areas for a long time to implement surveillance and detection features to promote d it has become a hot spot of hightech development in today’s world.UAV data link equipment is an important part of the system. When UAV system is in the process of mission, the measurement and control information transmission system is the only channel to link the UAV ground station and the UAV, bearing the task of UAV’s flight and the commond’s transmission about task control without interference, and bringing equipment status, surveillance data and other information collected by unmanned aerial vehicles back to ground station terminal safely.This article is a dedicated UAV data link RF channel module, compact design is best installed in a limited volume and weight of the UAV, is very suitable for small UAV applications. To achieve measurement and control information , and then to achieve real-time transmission. The module has an advanced digital design, general devices to low-cost and high precision civil structural design together to ensure that the RF module has a small, lightweight technology, etc. can be configured to meet the full UAV chain-specific usage requirements. Meanwhile, the module also has a veryhigh reliability and performance, is entirely practical engineering design products. In this paper, there is an analysis of the demand for the use of the RF module, proposed module design and the overall program. Combined with the structural characteristics of the RF module, provide the circuit of RF module and described instructions. Description the hardware design process; analysis operational experience, gives the RF module of the pilot projects and measurement methods, and analysis of experimental data given, In the last, prospect the development of the RF module and the UAV data link with the monitoring and control equipment.RF channel module has been applied in the monitoring and control of a small UAV data link . Its small size, low power, low cost meets the needs of users. To a certain extent, it becomes an alternative of similar foreign products.
