GLR Detector in Gaussian Interference Environment with AutoRegressive Spectrum in Multi-Channel of High-Frequency Surface Wave Radar

This article explores the M-AR-GLR detector with regard to the Gaussian spectrum on the actual sea clutter that is collected by multi-channel HFSWR. In this study, we will show that a large number of elements have no effect on the correlation matrix of interference samples that cause to reduce the compute volume. Spatial dependence of received sample is less, detector performance will be better. Since the detector performance with fewer number of secondary data is suitable, it can be used in HFSWR. Also in the small signal to noise ratios, the proposed detector can be better than Kelly's GLR [1].
