Abstract: With the great development of general aviation and rotor unmanned aerial vehicle, the urgent need is to guarantee the safety of airspace monitoring and management. Since radar has a wide tracking-blind area in low-airspace, radar echo will be disturbed easily by cluster waves which result in exception of the target information gathering. Large-scale arrangement of ADS-B system also has a limitation, thus research on low-airspace surveillance and management has been a hot topic nowadays. Here, a radar/visible light monitoring and tracking method is proposed, which targeting the rotorcraft in low-altitude airspace. Based on the framework of Tracking-Learning-Detecting（TLD）, the radar is set as main tracker and visible light sensor as detector. Measurement model switching and data online update can be completed through interactive multi-model method and PN-learning process, while making the target state information and monitoring/tracking system more accurate. The availability has been verified by results of numerical simulation.
