Abstract

The invention discloses a method for computer simulation of radio wave communication in bimodal terrain, the steps of which specifically include: S1, loading a three-dimensional digital map; S2, setting the positions of communication transmitters and receivers on the three-dimensional digital map; S3 . Set the working frequency of the communication equipment used by the communication transmitter and the receiver; S4. On the three-dimensional digital map, form a terrain elevation profile between the communication transmitter and the receiver; S5, according to the three-dimensional digital map and the terrain elevation profile, determine the bimodal terrain; S6, calculate the terrain attenuation correction factor A (U); S7, calculate the free space transmission loss of radio waves; S8, according to the terrain The attenuation correction factor A(U) and the free-space transmission loss are used to calculate the radio wave transmission loss; S9, use the radio wave transmission loss as the attenuation value of the radio wave communication to perform analog communication.

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 bimodal 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 tests efficiently and quickly, save costs, reduce manpower and material consumption, in order to solve one or m...
