Abstract
A method detects a target in a radar signal using space-time adaptive processing. A test statistic is T = max α max λ ∫ R f 1 ( x 0 , x 1 , … , x K ❘ α , λ , R ) p ( R ) ⅆ R max λ ∫ R f 0 ( x 0 , x 1 , … , x K ❘ λ , R ) p ( R ) ⅆ R , where x0 is a test signal, xk are K training signals, α is an unknown amplitude of a target signal within the test signal, λ is a scaling factor, R is a covariance matrix of the training signals, and a function max returns a maximum values. The test statistic is compared to a threshold to determine whether the target is present, or not.
