The Decorrelation Time Accumulation Restrain Method for Sea Clutter Spike

Modern wide-band radar system could resolve the refined sea surface structure, which results from the strong instantaneous clutter spike appearing in the background echo, and severely affects the target detection efficiency in searching process. It is important for radar design and efficiency-improving to investigate the high-resolution clutter restraint method. One of the typical restraint methods is decor relation time accumulation method, which can put down the clutter energy. This article studies its application on clutter-restraint and detection rate improvement of target detection in typical sea clutter scene. The detection effect under different-resolution in simulation spectacle is also studied, which shows that high resolution improved the right detection probability.
