电子干扰措施 meaning in English

ecm
electronic counter measures

In order to evaluate the electronic protection capability of the antiship missile active - passive multimode seeker , and also provide simulation data for the devising of the multimode guided antiship missiles , several studies are performed in this thesis : the modern ship ecms are systematically studied , and the electronic counter - countermeasures ( eccm ) of the active - passive multimode seeker are analyzed . a study is performed on the modeling and simulation ( m & s ) of the missile - ship engagement scenario . models needed for the engagement simulation are established
