Design of Hardware-in-the-loop Simulation System to UAV Automatic Landing Guidance

The design of UAV Automatic Landing Guide system is an important issue for large UAV automatic landing. A hardware-in-the-loop simulation system to UAV automatic landing guide was designed based on decimeter wave instrument landing. The simulation system could be used to design and test the stability, reliability and performance indicators of landing guidance system, but not spend a lot of financial and material resources of the development project and could avoid the risk of the actual test flight. The hardware-in-the-loop simulation system includes ground and airborne equipment of decimeter wave instrument landing, radio altimeter simulator, laser altimeter system simulator, and digital aircraft kinetic model and flight control system simulation. The hardware-in-the-loop simulation system realized whole process simulation of UAV automatic landing guide. The simulation data may take the important reference for material system.
