1090MHz-signal environmental evaluation system based on computer simulation

Abstract

The invention provides a computer simulation system for 1090MHz-signal environmental evaluation. According to the computer simulation system, firstly, a scene environmental model of an evaluation region is built, the airplane entry and exitrates and the airplane entry and exitroutes are adjusted to be adaptive to dynamic flight simulation of a future terminal entering an airspace condition, and the future airspace condition is adapted by adjusting a scene environmental configuration parameter; secondly, a receiving power model of a signal is built by combining target emission power, an antenna gain and a propagation loss and is used for judging whether the signal can be received and decoded successfully or not; thirdly, air-air and air-ground communication processes, namely signal transmission, propagation and receiving processes in the evaluation region are simulated and evaluated by a simulation method, and a dynamic 1090MHz-signal environment in the evaluation region is acquired by combining the scene environmental configuration parameter in the evaluation region, an airplane node state and a ground node state; and finally, an evaluation parameter of the 1090MHz-signal environment is acquired according to the counted received and decoded success rate and the statistics on the simulated 1090MHz-signal environment.
