Abstract:

The principle of setting a radar system's efficiency evaluating index is given based on the characteristics of the radar system.A system of index on radar system's comprehensive evaluating is built.Using the theory of center of gravity of cloud,this paper builds a cloud model on the character index and index of both character and quantity.Then,the center of gravity of multidimensional weighted cloud is calculated.A comprehensive evaluation of the efficiency of the phased array radar system is given,using the method of evaluating the center of gravity of cloud.

Key words: systems efficiency;evaluating;center of gravity of cloud
