Query: Impact of covariance mismatched training samples on constant false alarm
  rate detectors   The framework of this paper is that of adaptive detection in Gaussian noise
with unknown covariance matrix when the training samples do not share the same
covariance matrix as the vector under test. We consider a class of constant
false alarm rate detectors which depend on two statistics $(\beta,\ttilde)$
whose distribution is parameter-free in the case of no mismatch and we analyze
the impact of covariance mismatched training samples. More precisely, we
provide a statistical representation of these two variables for an arbitrary
mismatch. We show that covariance mismatch induces significant variations of
the probability of false alarm and we investigate a way to mitigate this
effect.
