Research on UAV Target Location Algorithm of Linear Frequency Modulated Continuous Wave Laser Ranging Method
摘要
The improved multi-track ranging target location algorithm is analyzed to achieve accurate location of typical obstacles in landing operations. On the basis of analyzing the requirements of typical obstacles on positioning accuracy and efficiency, the target positioning algorithm of multi-track ranging was improved to multi-machine positioning, and further improved to linear frequency modulated continuous wave laser ranging method. After in-depth study, the number of UAVs required at different altitude levels was given, and the positioning errors were constantly approaching the requirements of the positioning accuracy at the meter level of obstacles, and simulation verification and comparative analysis were carried out.
