Abstract
In calm conditions, synthetic aperture radar (SAR) ship wake images have the form of a bright "V," typically with a half-angle between 2 and 5 deg. The images sometimes persist for many miles behind the ship and are more likely to be obtained if the ship is traveling close to the azimuth direction of the radar than if it is traveling close to the range direction. Here it is shown that Bragg scattering from ship-generated diverging waves is consistent with observed images. Methods of calculating radar scattering cross sections for "idealized" conditions are developed and examples from their use are presented.
