Based on the quantitative analysis and linking to the combat command, it presents the tactical application principles of muti-vessel cross location using the ship-borne microwave OTH radar.

The paper analyzes the using principles and registering principles in the course of acquiring trade marks and holds that the combination of the using principles and registering principles is fair,reasonable and stable to law system.

Based on the tactical application of U.

The interference mechanism of infrared interference missile is analyzed, its composition, operation process, tactical application, main technical indexes and delivery/launch technology are briefly introduced, and the development trend of infrared interferenct missile is also analyzed.

The author summed up the jamming methods against IR-imaging missiles by analyzing the operational process,the guidance characteristics and the imaging conditions,which provides theoretical reference for development of jamming weapons and tactical operation.
