WebFeb 27, 2024 · A word of caution: the lemma of Barnes and Hoffman is not a generalisation of Gerschgorin disc theorem, because the union of all Gerschgorin discs always covers the spectrum of a matrix, but this is not the case in Barnes and Hoffman's lemma. WebWe begin with an important perturbation theorem for eigenvalues. Theorem 1 (Gerschgorin Circle Theorem) Let λ1,λ2,...,λ n be the eigen-values of A ∈ Cn×n. Deﬁne λ(A) = {λ …

WebThe problem of the constant false alarm rate (CFAR) detection of bistatic space based radar (B-SBR) is addressed under the background of strong and nonhomogeneous clutter. We propose a novel and simple cell averaging (CA)-CFAR-like (CA-CFAR-L) detection method based on the Gerschgorin circle theorem for B-SBR.
