Sea clutter characterisation & small target detection in maritime surveillance radar

Maritime surveillance radar experiences serious limitations imposed on their performance by unwanted sea clutter. Sea clutter limits the performance of the radar, so it is vital to understand the characteristics of sea clutter to improve the performance in detecting small targets. A detail analysis...
