LSS UAV target intelligent detection in urban complex environment

UAV detection and recognition in urban environment is an important part of civil UAV monitoring and countermeasures. This paper presents a method of target detection and extraction based on radar detection system. Firstly, a set of all-solid state portable surveillance radar system is designed based on modular design method. Then the strong clutter suppression method and the target detection method are researched. On this basis, the ICEEMDAN method and adaptive CFAR technology are adopted to reduce the false alarm rate and improve the detection accuracy. Finally, the results show that the proposed method can meet the requirements of high-precision detection of UAV in complex urban environment.
