Abstract
With the development of integrated joint operations technology, unmanned aerial vehicle (UAV) plays a more and more important role in modern warfare and civil science and technology. Compared with manned aircraft, UAV has many advantages in manufacturing and maintenance costs. However, the command and control of UAV depends entirely on the remote operation of ground control station, and its dependence on electromagnetic signals makes UAV more susceptible to interference and threat from complex external electromagnetic environment, and the consequences caused by interference are more serious, which may lead to control failure and crash. In this paper, the composition and characteristics of the complex electromagnetic environment faced by UAV are combed, and the interference coupling mechanism of UAV to external electromagnetic environment is studied. Furthermore, based on the interference coupling mechanism of complex electromagnetic environment to UAV, the anti-interference test of VUAV in complex electromagnetic environment is studied and carried out, and the anti-interference ability of UAV to signals of different systems is verified.
