Robust and effective detection of marine moving targets in the sea clutter is one of the fundamental and difficult problems in both military and civil fields. There are both advantages and limitations of classical radar detection methods. Sparsity has been proved as a promising tool to solve inverse problems for a high-resolution solution which mathematically may be nonunique. The main purpose of...
Robust and effective detection of “high-speed and highly maneuvering” target is one of the fundamental and difficult problems in both military and civil fields. Long-time coherent integration (LTCI) is proved to be an effective way to strengthen the weak signal and improve signal-to-clutter ratio. Recently, we have extended the concept of LTCI and proposed several methods for maneuvering target detection...
The micro-Doppler (m-D) signatures can describe the refined motion characteristics of a marine target, which are helpful for target detection and recognition. Due to the complex sea clutter and m-D of marine target, traditional detection methods using time-frequency analysis have great limitations on accuracy and computational cost. In this paper, the micromotion signal model of sea surface target...
