基于延迟自相关双门限的短波天线选择方法
A Selection Method for HF Antenna Based on Double Threshold Detection Theory of Delay Autocorrelation
摘要
Abstract
The high frequency( HF) fixed station is equipped with multiple transmitting antenna. In the ac-tual application,a fixed antenna is generally chosen to transmit signal according to the plan,which does not make full use of antenna directivity. As a result,the communication effect is not the best. In order to solve this problem, a detection mechanism is designed to evaluate the quality of transmitting signals between transmitter and receiver. Based on double threshold detection theory of delay autocorrelation,the quality of the probing signal of each transmitting antenna is judged. Then,according to the evaluation scores,the an-tenna with the best communication effect is selected automatically from the transmitting antennas. Without changing the existing configuration,the proposed method can greatly improve the quality of communication. The simulation results show that the proposed method is feasible and effective. It can improve the efficiency of antenna selection and make full use of antenna directivity to achieve the purpose of improving emission efficiency and communication effect at a lower cost.关键词
