In order to solve the signal attenuation and noise problems that often occur in the radio station in the process of long-distance communication,this paper uses interdisciplinary research methods,functional research methods,simulation and information research methods to study the short-wave antenna pan-tilt adaptive system.The functional composition and principle of the PTZ adaptive system are given.According to the functional needs of shortwave communication in the use process,based on the PID control algorithm,the shortwave adaptive technology and the PTZ technology are combined to form a new set of technologies,say,the shortwave pan-tilt adaptive system.The pan/tilt system can control the functional modules in the pan/tilt adaptive system while tracking the communication signal,and adjust the signal quality accordingly,so as to improve signal quality,reduce noise,improve system robustness and ensure signal stability.Through the research of the system,it is found that the shortwave antenna pan/tilt adaptive system can effectively solve the problem that the shortwave antenna cannot be adaptively adjusted during the working process.The system is flexible in installation and use,and has good versatility and applicability as a whole.This research has good application prospects.
