Method for simulating radio wave communication in forest terrain by computer

Abstract

The invention discloses a method for simulating radio wave communication in forest terrain by a computer. The method specifically comprises the following steps: S1, loading a three-dimensional digitalmap; S2, setting positions of a communication transmitter and a communication receiver on the three-dimensional digital map; S3, setting the working frequency of communication equipment used by the communication transmitter and the communication receiver; S4, judging the terrain of the forest region according to the three-dimensional digital map; S5, calculating a terrain attenuation correction factor Lt; S6, calculating the free space transmission loss of the radio wave; S7, calculating the radio wave transmission loss according to the terrain attenuation correction factor A(U) and the freespace transmission loss; and S8, taking the radio wave transmission loss as an attenuation value of the radio wave communication to carry out analog communication. According to the adopted method forsimulating the radio wave communication in the forest terrain by the computer, and the life safety of communication personnel is effectively guaranteed. According to the invention, integration and calculation of special test acquisition information can be completed efficiently and quickly, the cost of a communication test is saved, and the consumption of manpower and material resources is reduced.

Description

technical field [0001] The invention relates to a command system communication test method, in particular to a computer simulation method for radio wave communication in forest terrain. Background technique [0002] The current situation of the communication test of the command system is that communication professionals bring communication equipment to the designated communication test site, and the special test can only be continued according to the terrain conditions of the test site and the information of the communication equipment. However, due to the complex and dangerous topographic conditions of the test site, this special test method that requires on-site inspections by communication personnel is very dangerous, wasting manpower and material resources and increasing test costs. [0003] How to ensure the safety of communication personnel, complete special experiments efficiently and quickly, save costs, reduce manpower and material consumption, in order to solve one...
