Analysis of the Electromagnetic Field Strength of Ultra-low Altitude Platform on Sea Surface

When the ultra-low-altitude platform is working at sea, the multi-path effect of radio propagation caused by ocean waves makes the received signal change dynamically, which adversely affects the normal operation of the receiver. For this reason, this paper uses the simulation method to study the characteristics of the coupling energy of the front door of the ultra-low-altitude launch platform by dynamic ocean waves. First, random ocean wave data under high sea conditions were generated, and an electromagnetic model for radio wave propagation simulation was established; secondly, the signal field strength data at the front door of the launch platform was calculated based on a high-frequency approximation algorithm; analysis is made and the variation law of signal field strength under typical sea conditions is given.
