Improvement of SAR/ISAR simulation in MOCEM V4.5 by computation of the ship Bow wave
2019 International Radar Conference (RADAR)(2019)
摘要
In the DGA simulation software MOCEM, signature of a moving ship takes into account several coupling effects such as the dihedral effect between the sea and the hull or the kelvin wakes. But in airborne SAR/ISAR images, we sometimes observe a Doppler spreading that generates a defocusing phenomenon at the bow of the ship, associated to the bow wave. Here we present the improvements done on the simulation to reproduce this effect.
