A multi sensor and multitarget identity recognition method based on range resolution is presented for multitarget measuring data correlation.The range resolution of each sensor is analyzed. The multitarget identity recognition method based on time sequence is proved correct in theory. Simulation results show that echo wave sequence of each sensor is the same in typicality aircraft formation. The method is proved correct and with high project value.

Modern warfare is a confrontation between weapon systems, which objectively, scientifically and comprehensively measures the performance of weapons, or pays great attention on evaluating comprehensive performance of weapon systems at the beginning of designing and requirement phase. It is very important to reduce the risk of developing new weapons and technology and improves economic efficiency. This essay focuses on study of future newly evented antiaircraft missile weapon's system contribution rate to antiaircraft missile weapon system by analyzing on establishing weapon system contribution rate evaluating frame. It depicts weapon system contribution rate from five aspects including function and performance, technological regimes, structure of system, efficiency analysis and cycle of economic benefit, which theoretically supports on evaluating the performance of future newly evented antiaircraft missile weapon.
