L. Shemer et al., SIMULATION OF SHIP WAKES IMAGE BY AN ALONG-TRACK INTERFEROMETRIC SAR, International journal of remote sensing, 17(18), 1996, pp. 3577-3597
A mathematical model that allows simulations of the image of waves in
ship wakes by either regular or interferometric airborne Synthetic Ape
rture Radar (SAR or INSAR) is described. The three-component velocity
held induced at the ocean surface by a moving ship serves as the input
to the model. The simulations take into account the effect of tempora
l variations of the wave held in the wake on the INSAR imaging by the
velocity bunching mechanism. The model also accounts for the scanning
distortion of the image. The developed algorithm allows study of the v
isibility of the ship wave wake by a regular SAR or by INSAR for arbit
rary imaging parameters, as well as for different ship sizes and ship
velocity vectors relative to the platform flight track. Various patter
ns of ship wake images obtained by numerical simulations are presented
.
