Matched subspace detectors

  title={Matched subspace detectors},
  author={Louis L. Scharf and Benjamin Friedlander},
  journal={IEEE Trans. Signal Processing},
In this paper we formulate a general class of problems for detecting subspace signals in subspace interference and broadband noise. We derive the generalized likelihood ratio (GLR) for each problem in the class. We then establish the invariances for the GLR and argue that these are the natural invariances for the problem. In each case, the GLR is a maximal invariant statistic, and the distribution of the maximal invariant statistic is monotone. This means that the GLR test (GLRT) is the… CONTINUE READING
