WebAbstract: We investigate the potential of k-nearest neighbor (KNN) based decision algorithms to detect a coherent signal in presence of non-Gaussian clutter, modeled in terms of a K-distributed spherically-invariant random vector (SIRV), plus thermal noise. The decision rule is fed by commonly used statistics, i.e., modified adaptive coherence … Webis to determine the statistics of the MLE of in the high SNR context. To this end, we follow step by step the outline of [2] and show that, in this low noise level regime, the MLE belongs to the class of elliptically distributed random vectors with a distribution intimately linked to that of the noise. Moreover,
