On developing a high efficiency radar system on a ship, the relationship between characteristics of the electromagnetic wave (hereafter we say "EM-wave" in distinction from waves on sea level) propagation and the wave height of the sea should be understood correctly. Ray tracing above rough sea surfaces model is often used for analyzing this problem, however the limit of application is not clear. In this paper, we show the characteristics of the EM-wave propagation above sea level calculated by ray tracing with rough sea surface model, and compare it with the result obtained by parabolic equation method.
