New synthesis time accumulation sea spike restraint method

Sea clutter spike has more negative impact as maritime radar resolution improves, which could cause target detection error or tracking miss. Imaging mode has been gradually utilized in order to improve target detection ability in sea background. Decorrelation restraint method has been developed to suppress sea spike, but its effect has not been studied thoroughly. Our work proposed a new synthesis spike restraint method combined time decorrelation accumulation with improved self-adaptation multi-scale filtering algorithm in sea image target detection and tracking process. And its improvement to detection performance is evaluated, providing reference for spike restraint measurement and sea target stealth technology development.
