Hello. I know that this kind of multipath may happen for airborne EM radar in a look-down configuration (versus the target) over a rough relief, but would it be possible for sound waves propagating in water and sonars (more curvy waverays than EM waves propagating in the air) over a rough seafloor ?
If yes, the waveform detection would be correct but the AoA would be largely biased... and I wonder if the new Thales sonar signal processing can/do make use of the real bathymetry as it was measured during the 1st phase.
