IPC: G01S7/02
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To precisely estimate the principal wave direction of an arrival wave having high correlation. SOLUTION: An arrival wave number determination part 10 calculates a ratio Er between a maximum value and the next maxim value of a characteristic value of a covariance matrix R of a M-element array reception signal so as to compare it with a predetermined value Dr. When he ratio Er is not less than the predetermined value Dr, the number of arrival waves is determined to be one, while the number of incoming waves is determined to be M-1 when the ratio Er is less than the value Dr. A virtual linear array conversion part 12 converts reception signals ranging from 2-1 to 2-M of a circular array into virtual linear array reception signals. An arrival wave power estimation part 13 estimates arrival wave power at an angular interval Δθ.  An arrival direction estimation part 11 computes an incoming direction estimation function F(θ) at an angular interval Δθ while using a matrix ES consisting of S eigenvectors in the covariance matrix R as a signal characteristic spatial matrix and using a matrix EN consisting of (M-S) eigenvectors as a noise characteristic spatial matrix if the incoming wave number determination in the incoming wave number determination part results in an S-wave. A principal wave direction estimation part 14 combines the computed value F(θ) in the arrival direction estimation part 11 and the computed value in the incoming wave power estimation part 13 together so as to determine its maximum value direction as the principal wave direction estimation result.
