Title:
EXPECTED-POWER-VALUE ESTIMATION DEVICE AND EXPECTED-POWER-VALUE ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162174
Kind Code:
A1
Abstract:
An expected-power-value estimation device (2) is configured so as to include: a covariance-matrix calculation unit (11) that acquires, from a receiving array antenna (1) that receives reflected waves coming from a target, signal vectors of the reflected waves and that calculates a covariance matrix of the received signal vectors; and an unwanted-vector-value exclusion unit (12) that excludes, from a plurality of vector values that array manifold vectors of the receiving array antenna (1) could take, vector values that are present inside the convex hull of the array manifold vectors. In addition, the expected-power-value estimation device (2) includes an expected-power-value estimation unit (13) that estimates expected power values of the reflected waves by employing, among the plurality of vector values that the array manifold vectors could take, vector values that are not excluded by the unwanted-vector-value exclusion unit (12) and the covariance matrix calculated by the covariance-matrix calculation unit (11).
