Abstract :
Current data collection and processing technologies, along with the use of high resolution spectral techniques, make it possible in many cases to obtain estimates of the Kelvin wave amplitude function A(θ), ship speed U, and ship heading α from SAR images of ship wakes. From this information, this paper presents a series of methods for deriving additional hull characteristics such as the length L, volume V, and offsets ζ(x,z)
