The Influence of Wave Spectrum and Antenna Attitude on the Offshore Electromagnetic Spectrum Distribution

The research of offshore electromagnetic spectrum detection methods is of great significance for improving the utilization of offshore electromagnetic spectrum resources, improving the quality of offshore communications, and controlling electromagnetic spectrum resources. This paper combines the Pierson-Moscowitz (PM) wave spectrum model and the antenna attitude to establish a offshore electromagnetic spectrum distribution prediction model based on the ray tracing method to improve the accuracy of the large-scale offshore electromagnetic spectrum distribution prediction. The influence of the maritime environment and antenna attitude changes on the offshore electromagnetic spectrum is studied. The test data shows that the wave spectrum and antenna attitude have a key decisive effect on the offshore electromagnetic spectrum distribution.
