Design And Implementation Of Monopulse-secondary Radar Based Uav Auto-landing Guide System

The application of UAV in recent years has experienced a substantial growth, and the spectrum of UAV has also seen a large expansion. When pilot intervention is required in the UAV control loop to conduct a Man-in-the-Loop UAV landing control, fligh safety hazadous accidents are likely to be evoked because of the time-delay in control and the limit in pilot situation-awareness. The need to study the auto-landing guide system is urgent.In order to solve UAV auto-landing guide problem, a guide system mainly based on Monopulse Secondary Radar and DGPS is proposed in this article. The system design, along with system application and data analysis are the main working subject, a UAV auto-landing guide system based on the analysing of Monopulse Secondary Radar and DGPS theory is designed, and the prototype system is completed, the system perfomance is examined in test flights.The main content is:1、System Requirement Analysis, the design direction is determined;2、Analysis on main technology, the priciple of Monopulse Secondary Radar, Differential GPS and the position deviation is studied;3、Project design of the guide system, based on Monopulse Secondary Radar and DGPS combination, and implement the system prototype.4、Study on runway measure and Monopulse Secondary Radar calibrate method, and analyze the positon deviation of the data accquied during the test flight.
