| Popis: | Ultraviolet (UV) Communication is a communication mode used 200nm˜280nm wavelength ultraviolet light as an information carrier. It has the advantages of all-weather operations, non-line-of-sight (NLOS) communication with a wide field and strong anti-interference ability etc. Solar blind characteristics can achieve anti-collision in unmanned aerial vehicles (UAV) formation flying. The distance calculation formula for line-of-sight (LOS) and NLOS is analyzed. One kind of three dimensional (3D) localization algorithm based on wireless UV communication is put forward. UAVs need anti-collision and location methods to ensure flight safety when flying or performing tasks in a complex atmospheric environment. Computer simulation result shows that the ranging precision of UV ranging algorithm can reach 3m, The node localization accuracy rate of localization algorithm can reach more than 80%. Numerical simulation results show that the localization algorithm has a high location accuracy, which can meet the requirements of anti-collision in UAV formation. |
