This paper proposes a fast numerical method for computing radio wave propagation in environments where a large number of transmitters, receivers, and obstacles move in a complex manner.
Ray tracing, one of the methods used to analyze radio propagation, is a high-frequency asymptotic technique that treats radio waves as rays. It searches for paths from a given transmitter to a receiver and calculates the electric field and received power at the receiver. It has been widely studied mainly in the fields of radio propagation analysis and computer graphics.
In both computer graphics and radio propagation analysis, fast methods geared toward real-time processing have been studied. However, to the best of the author’s knowledge, methods for real-time radio propagation computation in environments with many moving objects have not yet been proposed.
Accordingly, this paper proposes a fast analysis method for radio propagation in environments with multiple moving objects by using, at each discrete time step, a technique that computes the propagation paths at the next step based on those calculated at the previous step.
Furthermore, we applied the proposed numerical method to a model simulating a factory environment containing moving objects, and estimate the validity of the proposed method.
