According to the theory of systematic engineering, by combining tactic and technology, this paper proposes some top design on how to protect the land-based radar information grid through electro-optic protection.

Development and testing of integrated laser protection and warming system;

Laser protection thin film for satellite-borne remote sensing instrument;

Study on a kind of novel visual laser protection system;

Discussion of electromagnetic protection in high electromagnetic fields environment;

So it is necessary to do the researches on the interferences on communication by electrified railway,and electromagnetic protection of the communication system in order to pro.

On this basis,the superiority of the trends of using engineering plastics as ammunition packaging were discussed,also the electromagnetic protection requirements were analyzed.
