An algorithm of sorting the phased array radar signal based on RST

The aim of This paper is to sorting the phased array radar signal. The method is using the radar beams scanning characters of the phased array radar, then proposes an algorithm based on the rough sets theory to sort the signal of phased array radars. From researching on the characters of the phased array radar´s beam scanning manners, we can use the PDW received from the receiving equipments as a set of attributes. Through using RST to reduce the attributes of phased array radar signal, we can get the rule of the attributes´ nucleus. So we can sort the phased array radar signal from the electromagnet environment from using the rule. Through experiments showed that this method can get a good result and can efficiently sort the phased array radar signal.
