The spoofing system and interference capability of unmanned aerial vehicle (UVA) attract more and more attention in the modern war. And the unmanned aerial vehicle navigation spoofing system based on satellite navigation signal is put to wide use because of a series of advantages, such as its better spoofing effect, smaller secondary damage, and lower equipment cost. However, problems do exist in the spoofing equipment of unmanned aerial vehicle at present, including the very single way of detection, poor camouflage of spoofing signal, lack of platform mobility, bad result of spoofing effectiveness and so on. This paper deals with the vehicular UVA navigation spoofing system on the foundation of upgrading its system’s maneuver capability. Meanwhile, the spoofing signal on camouflage, fusion analysis of photoelectricity radar detection and other researches have been carried out. As a result, it forms high accuracy of UVA spoofing capability by means of outfield experiment, and also verifies availability of the system.
