Array shape self-calibration technique for direction finding problems

摘要: In the paper a self-calibration technique is proposed to handle bearing estimation problem involving unknown perturbed sensor location. This calibration applied on MUSIC estimator in finding direction of arrival (DOA) plane waves white noise. The basic idea maximise total output power from directional or frequency regions interest while imposing constraints length projection signal position vector (SPV) noise subspace. exhibits relatively stable performance over other existing techniques sense that it converges required solution consistently. However, this achieved at expense heavy computational load. illustrated with numerical results obtained computer studies conducted.
