Abstract

In this paper, we review and compare the state-of-the-art target detection algorithms. We introduce a new target detection workflow incorporating a Minimum Noise Fraction (MNF) transform before target detection. Applying a MNF transform was found to improve the detection results in general, especially with the Orthogonal Subspace Projection detector. In this paper, we propose a new algorithm - Mixture Tuned Target-Constrained Interference-Minimized Filter (MTTCIMF). MTTCIMF uses the MNF transformed image as the input and combines the mixture tuned technique with the TCIMF target detector. By adding an additional infeasibility band, mixture tuned techniques improve the detection results with a reduced number of false alarms. A HyMap data set with ground truth is used in the comparative study. Quantitative and visual evaluation of different algorithms is given. A new quantitative metric is proposed to evaluate the visibility of targets in the detection results. Keywords: target detection, mixture tuned matched filter (MTMF), mixture tuned target-constrained interferenceminimized filter (MTTCIMF), minimum noise fraction (MNF), adaptive coherence estimator (ACE), orthogonal subspace projection (OSP), constrained energy minimization (CEM), target visibility
