Abstract :
The spectral characteristics of sea clutter echoes and man-made noise disturbance in the HF band are analyzed. A new spectral method for ship detection in heavy sea clutter and man-made noise environment by an onshore ground wave radar is introduced. A T-R cell averaging detector with the assistance of a spectrum monitoring system operates on a frequency agile mode, and it can detect ships even if they are masked by the first-order Bragg spectra of sea clutter echoes
