An algorithm of signal sorting and recognition of phased array radars

This article uses the radar beams scan characteristics of the phased array radar, and proposes an algorithm based on the rough sets theory to sort the signal of phased array radars. From the research of the character of the phased array radar´s beam scanning manners, and use the PDW received from sensors as the set of attributes. So we can sort the phased array radar signal from the environment.
