Analysis and troubleshooting methods of typical cases of SWR faults in a certain HF radio set
Short wave(high frequency)signal has good diffraction performance and can be reflected by the atmospheric ionosphere,so it is often used in over the horizon long-distance communication.During the use of an airborne short wave radio station,there are many reasons for the failure of standing wave ra-tio exceeding the standard,which affects the normal use of the system.This paper analyzes and combs several typical cases of standing wave exceeding standard fault of airborne short wave radio,establishes standing wave exceeding standard fault tree combined with its working principle,and forms a set of effec-tive troubleshooting scheme.By establishing the analysis and treatment method of fault tree,we can deeply understand the working principle and key performance of short wave radio,and give practical and effective troubleshooting paths and treatment methods for exceeding standing wave ratio,which has cer-tain guiding significance for relevant professionals to troubleshoot and deal with such faults.
