The distinguish and statistical analysis of sea clutter spikes

The current study shows, as the "sea spikes" like the target signal, there is great impact on target identification, Therefore, the identification of sea spikes is particularly important. it is possible to separate the spikes from the sea background by using three sea-spikes defining parameters, the spike amplitude, the minimum spike width and the minimum interval between spikes. We pay attention to the spike duration and the interval between spikes in the paper, in addition, we also conduct a statistical analysis to the condition of sea spike happens and get the conclusions.
