Abstract

Aiming at the problem of poor detection of slow speed targets in sea surface under complex sea conditions for airborne maritime surveillance radar, this paper first analyzes the distribution characteristics of sea clutter in different sea conditions, studies focus on inter-scanning coherent processing, non-coherent processing and frequency agility processing. Finally, the results of three methods, such as non-coherent accumulation, constant frequency coherent accumulation and fixed frequency non-coherent accumulation, are analyzed and compared under different sea conditions. It is concluded that under low sea conditions, the method of coherent accumulation and increasing the number of pulse accumulation can effectively detect the slow target of the sea surface.
