A Method of Computer Simulation for Radio Wave Communication in Forest Terrain

Abstract

The invention discloses a computer simulation method for performing radio wave communication in a forest terrain. The method specifically includes the following steps: S1, loading a three-dimensional digital map; S2, setting the positions of a communication transmitter and a receiver on the three-dimensional digital map; S3, setting the operating frequency of the communication equipment used by the communication transmitter and receiver; S4, judging the terrain of the forest area according to the three-dimensional digital map; S5, calculating the terrain attenuation correction factor Lt; S6, calculating the free space transmission loss of radio waves, S7. Calculating the radio wave transmission loss according to the terrain attenuation correction factor A(U) and the free space transmission loss; S8. Using the radio wave transmission loss as the attenuation value of the radio wave communication to perform simulated communication. The invention adopts the method of computer simulation to carry out radio wave communication in forest area terrain, which effectively guarantees the life safety of communication personnel. The invention can efficiently and quickly complete the integration and calculation of information collected by special tests, save the cost of communication tests, and reduce the consumption of manpower and material resources.

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...
