The main subject of the research on the damage efficiency is the deep research on the anti-Missile efficiency of the proximity fuzed ammunition.

To study the combat of proximity fuzed ammunition, the combat effect calculation is the key.

The rsearch on time-fuzzed ammunition hitting on the target is the basic of fire effect evaluation.

Analysis of development in proximity fuze of aerial defence missiles;

Combined with the principle of capacitance proximity fuze,four key technologies are analyzed,including the optimum height of burst of fragmentation mortar,control signal processing,directional detection circuit design and antijamming,in the design of capacitance proximity fuze of mortar.

It is difficult to adjust the demodulation voltage for a certain proximity fuze,which cause low function reliability.

Concrete application of themethod in capacity proximity fuzes is described, and it has been shown to bepracticable from results of firing tests.

On the basis of analyzing two series of south Africa aircraft bomb fuze from their structure characteristic, working environment, working principles, features and so on, this paper puts forword some suggestions for the development of our aircraft bomb fuze fechnology.
