A criterion to detect sensor array distortion

摘要: The authors present a criterion to detect displacements of the sensors along array. This relies on new source bearing estimation technique which is less accurate than most high-resolution (HR) methods but much more robust sensor array distortion. By comparing estimates obtained by HR method and this method, test can be defined decide whether shape distorted or not. A theoretical study estimator as well that proposed are provided. Simulation results given illustrate behavior for various distortions. >
