Abstract： At present, in the simulation of sea surface echo signals in radar systems, target echo models are established only based on parameters such as distance and relative motion speed. However, in reality, the echoes detected by radar on the sea surface not only include ship targets, but also electromagnetic scattering of waves, resulting in complex detection environments. This article uses composite electromagnetic scene simulation calculation technology to calculate the scattering scene of targets and sea surface coupling under low sea conditions, achieving radar cross section estimating and imaging, high-resolution one-dimensional range profile imaging and inverse synthetic aperture radar imaging of certain typical military targets and background environments. Simulation results of the target were analyzed.
