In a sonar system using a large array multielement sonar detector, the raw phase and intensity data is reduced to less than three bits per channel per slice for each of the detectors in the multielement array before the raw data is transmitted to a beamformer for transforming the data to information about the spatial positions of objects reflecting the sonar signals.

A survey system including a multibeam echo sounder having a single projector array and a single hydrophone array constructs a multi-component message for ensonifying multiple fans and deconstructs a corresponding message echo for use in analyzing the returns from each fan.

A survey system including a multibeam echo sounder and a beam selector for selecting beams with the largest amplitudes.

Beamformed sonar data is compressed before communicating the data to a storage step or to a further processing step. At lease some of the beams of the compressed beamformed data have values for at least two different ranges.

Disclosed is a method for transmitting data via a vehicle data bus from an ultrasonic system, which comprises at least one ultrasonic transmitter and an ultrasonic receiver, to a data processing device, wherein predetermined signal profile characteristics are extracted from the echo signal received by the at least one ultrasonic receiver of the ultrasonic system. Echo signal data, which represent signal profile characteristics extracted from the echo signal, is created. Said echo signal data is transmitted from the ultrasonic system via the vehicle data bus to the data processing device.

A method for operating an ultrasonic measuring device, encompassing the steps of receiving echo amplitudes, ascertaining object distances for the received echo amplitudes, computing normalized echo amplitudes for the received echo amplitudes, a received echo amplitude with a certain object distance being divided by a reference echo amplitude for the same or a similar object distance, encoding the normalized echo amplitudes, and transmitting the encoded echo amplitudes to a control unit. Also described is a related computer program, a system for carrying out the method, and a vehicle that includes a driving assistance system.
