Comments on "Probabilities of false alarm and detection for the NAMF operating in Gaussian clutter"

In the above-named letter [ibid., vol. 14, no. 11, pp. 864-866, Nov. 2007], Nadarajah derived explicit expressions for the probabilities of false alarm and detection of the normalized adaptive matched filter (NAMF) in Gaussian clutter. However, there is an error in the derivation of the expression for the probability of false alarm. The purpose of this comment is to correct the error.
