Performance of Low-rank STAP detectors
conference paper
In this paper the STAP detector based on the lowrank
approximation of the normalized adaptive matched filter
(LRNAMF) is investigated for its false alarm probability (FAP)
performance. An exact formula for the FAP of the LRNAMF
detector is derived using the g-method estimator [4]. The non CFAR
behavior of this detector is shown via simulations using
different models for the clutter-plus-noise covariance matrix. The
detection probability is also evaluated, and the LRNAMF detector
exhibits robustness in the presence of inhomogeneities consisting
of interferers in the training data, for both non-fluctuating as
well as fluctuating target models.
