Multiple signal detection and parameter estimation using sensor arrays with phase uncertainties

In this paper a procedure is outlined for performing both sensor array calibration and signal detection/direction of arrival estimation simultaneously. The source directions are unknown. Sensor array calibration is done using a least squares technique. Signal detection and direction of arrival estimation is performed by a multiple test procedure based on F-tests. The algorithm is studied by simulations and by numerical experiments with data measured by an experimental radar array with 8 elements.
