Sonar method for detecting and / or determining the position and / or speed of objects underwater in a specified region, sonar assembly, and receiving unit

A sonar method and assembly for detecting and / or determining the position and / or speed of objects underwater and / or on the water in a specified region. The orthogonality of Doppler-shifted transmission sequences is explored. First, a transmission sequence is generated, spread for some possible Doppler shifts and output via the transmission elements. If the transmission sequence is chosen carefully, the spread versions become orthogonal to each other and enable MIMO signal processing. If one of the assumed spreads matches the speed of the object, the spread is canceled out again to form the original transmission signal. This allows the binary detection of the presence of an object with the correlation of only one sequence and reduces the computing effort at the respective receivers enormously.
