Analysis of Sea Surface Floating Ice on The Electromagnetic Scattering of Ship

This paper analyzed the effect of sea surface ice on the electromagnetic scattering of ships in low grazing angle incidence. The three-dimensional geometric model of patrol boat, rough sea surface and floating ice was established, and the X-band radar cross section of patrol boat in the typical sea ice distribution was calculated. The results of the simulation show that the effect of floating sea ice on the radar cross section of ship is about 10dB difference in the two designed scenarios. The results can provide technical support for the statistical analysis of radar detection for ships sailing in polar area.
