Abstract :
Sources of error in practical beamforming arrays are identified and quantified. Three optimal beamforming techniques are compared and contrasted in the presence of these errors, and examples of their performance are given. The strengths and weaknesses of these techniques are identified and critiqued. The importance of incorporating calibration data into the beamforming algorithm is illustrated, and an effective technique for doing so is given.<>
