The Research Of Measurement System Of Azimuth Angle By Photoelectric Signal For Unmanned Aircraft Takeoff And Landing

With the rapid progress of application in UAV, the research and realization of landing control techology have been highlighted in embedded systems. This article studied on the control of UAV rollout rectification, using the principle of wireless radio interferometer to design the photoelectric system and pseudo random code to rectify the lateral—angle.At first, this paper introduces the composition of the mearsurement of lateral—angle system and gives a brief introduction of its partial function and the relationship among them. The following two parts are the central contents of this paper that are the hardware design and debug processing. In the system, the hardware is mainly made of the photoelectric system and processor FPGA and relevant components and sensors.In addition to the completion of the system tasks, proposed the innovation: according to the principle of wireless radio interometer, used the photoelectric system to replace the wireless radio system. There are some advantages on the photoelectric system:1. High precision on the angle discrimination of the photoelectric system.2.Wide bandwidth on siginal of the photoelectric system, leading to high precision on the distance.3. High working frequence of the photoelectric system, leading to good immunity.4. The photoelectric system works passively, and has good concealing.5. The photoelectric system works all time, extending visional ability at night.6.The photoelectric system has small size, light quality and quick reaction.
