Abstract [en]

In hydro-acoustic array signal processing we are often concerned with accurate determination of signal parameters from array measurements. To obtain accurate direction estimates, knowledge of the array response is required. Most estimation techniques are sensitive to errors in the array response model. Thus, reliable array calibration schemes are of great importance. In practice, calibration is done by measuring the array response when only one emitter is present and the signal parameters of which are allowed to vary in a known way. Herein, methods for generating an array model from noise corrupted calibration vectors is developed. The performance of the technique is examined on data collected from a full-scale hydro-acoustic array.
