摘要：
This paper deals with the analysis of coherent spiky sea clutter data recorded by a high range and Doppler resolution airborne radar for maritime surveillance mission at low grazing angle. A general description of sea-spikes is given: physical explanations, statistical modelling and identification with three different methods. The following properties are then analysed for our data: 1/ temporal characteristics such as radar cross section, range spread, life time and pulse to pulse correlation with frequency agility, 2/ spectral characteristics such as mean frequency and Doppler spread.
