Wireless electromagnetic coverage area calculation method under line-of-sight communication

Abstract

The invention provides a wireless electromagnetic coverage area calculation method under line-of-sight communication. The method comprises the following steps of: resolving a sight distance communication radio frequency coverage area under different altitudes by matching terrain height data according to the longitude and latitude, height of a central point and a maximum unshielded communication distance; the method can meet the calculation requirements of a radio station transmitting electromagnetic coverage area in a laboratory and in a practical application process, and can quickly and efficiently assist a user in positioning and checking whether communication interruption is caused by a space shielding problem or not according to a calculation display result of the electromagnetic coverage area. According to the method, whether the reason of actual line-of-sight communication interruption is caused by space shielding can be effectively and visually analyzed in an assisted manner; aconvenient and effective technical means is provided for eliminating space occlusion, so that the space occlusion problem in the sight distance communication process is changed from the original subjective qualitative analysis to the quantitative analysis supported by the data analysis result.

Description

technical field [0001] The invention belongs to the technical field of radio station communication transmission, and relates to various technologies such as wireless networking, information transmission, anti-interference, coordinate system transformation, and line-of-sight communication guarantee. Background technique [0002] In the process of data station networking for line-of-sight communication, due to the limited conditions of use of the station itself and the combined influence of factors such as the complex working environment of the outside world, there are often many reasons that may cause the communication between stations to fail, such as The power amplifier of the transmitting station is faulty, the receiving channel of the receiving station is faulty, and for example, in the TDMA communication system, the time of the receiving station and the generating station is not synchronized, or two stations send messages to another station at the same time, causing multi...
