- Abstract
Because Ku-band satellite relay is adopted, there are many problems in the over-the-horizon communication system of high-altitude long-endurance unmanned aerial vehicle(UAV), such as limited available signal bandwidth, numerous interference sources and large airborne terminal equipment. For this situation, a new overall and sub-system realization scheme for UAV over-the-horizon communication system based on Ka-band satellite is proposed and a few key design elements are given as well. With detailed derivation of the link calculation formula, by taking the forward rate of 51.2 kb/ s and the return rate of 8 Mb/s for example, link budget and numerical simulation analysis are performed. Comparison with the traditional Ku-band scheme in transmission speed, anti-interference capability and antenna aperture indicates that the performance of the designed system can be improved by about 20%. The rationality, feasibility, effectiveness and engineering feasibility of the scheme is verified by flight test, which provides the thought and reference for the overall design and engineering implementation of UAV-borne over-the-horizon communication system.
