Abstract
The sounder according to the invention comprises two transmit-receive antennas (1, 10) whose respective axes are off-target toward the front, in the direction of movement of the platform, these axes being symmetrical relative to a straight line (3) passing through their intersection and parallel to the axis of travel of the platform, the transmit frequency of the first antenna, equal to the receive frequency of the second being different from the transmit frequency of the second, the latter frequency being equal to the receive frequency of the first.

A multibeam sounder for taking submarine predictive soundings, placed on a marine or submarine platform, comprising:
- two transmit-receive antennas, namely a first antenna and a second antenna, whose respective axes are off-target toward the front, in a direction of movement of the platform, the axes being symmetrical relative to a straight line passing through an intersection of the axes and parallel to an axis of travel of the platform, the first and second antennas being arranged to each have a transmit frequency and a receive frequency different from its transmit frequency, the transmit frequency of the first antenna being equal to the receive frequency of the second antenna, and the transmit frequency of the second antenna being equal to the receive frequency of the first antenna.
