Abstract:

An array of high-resolution location techniques, such as radar, sonar and seismic signal processing, are of great interest in many fields in recent years. A new method of removing noise, which is based on multitarget array covariance matrix of received signals, is developed in this paper. The results obtained by the method are simulated by the computer.

Key words: Covariance matrix, Signal subspace, Noise subspace, Singular values decomposition （SVD）
