Research on a New Air Moving Target Information Acquisition Algorithm
Based on the characteristics of small radar cross section, high speed of air moving target, the existing condition of shitty target detection effect and low detection efficiency of those conventional radar and infrared means, a new algorithm of acquiring air moving target information based on wind field disturbance detected by lidar is proposed. The basic principle and main process of moving target information acquisition based on wind field disturbance is given. Through receiving the laser echo signal reflected by atmosphere and the retrieval algorithm of radial and horizontal wind speed, the wind field distribution in scanning area can be acquired. Meanwhile, the disturbance wind field can be acquired by filtering background wind field, the location and attribute of target can also be obtained based on the moving target information acquisition algorithm. The experimental result shows that the target location is the radial distance of 800 m and the pitching angle of 82°drawn by this algorithm is the same as the practical situation. Consequently, this new means of target detection is practicable, which will offer a brand-new path of detecting and discovering air moving target efficiently in the future.
