A multichannel auto-regressive GLR detector for Gaussian Spectrum Interference in HFSWR

The HF surface wave radar, due to its transcendental horizon, makes it possible to detect the targets that the horizon prevents them from detecting in a vast area of the ocean and sea. However, in the event of high level of interference with colored clutter, the efficiency of detecting conventional processes (which is dependent on data) is reduced. Also, the Bragg component of the sea is another factor that prevents the detection of targets. In this paper, the general - purpose M-AR-GLR detector is used in a special case for HF surface wave radar and on the practical samples of sea clutter. It has been shown that with increasing the number of received pulses, the efficiency of detector becomes better. The efficiency of detector is improved by reducing the spatial dependency of the received samples. The detector maintains its performance with little secondary data. In the little signal to interference ratio, the proposed detector maintains its efficiency and is better than the GLR's Kelly. Hence, this detector is effective for sea clutter and HF surface wave radar.
