Joint Ship Detection Based on Time-Frequency Domain and CFAR Methods with HF Radar
Remote Sensing, 2021 Compact high-frequency surface wave radar (HFSWR) plays a critical role in ship surveillance. Due to the wide antenna beam-width and low spatial gain, traditional constant false alarm rate (CFAR) detectors often induce a low detection probability.
