In the paper,make design of an anti-tank missile proportional navigation loop of final guidance,guidance design includes guidance filter design,varying gain compensation signal in proportional navigation loop design and damping loop design.

In order to describe the design method of the self sustained oscillations damping loop,the loop based on solid gas vane is designed,the design method and the design procedure of the correction parameter of the damping loop are described in detail,and the damping loop is emulated.

The research progress of high damping magnesium alloys and magnesium based composites is briefly introduced in this article, and the influence of strain amplitudes, frequency, temperature, heat treatment and ingredients on the damping property of magnesium alloys is discussed, and the damping mechanisms and damping design of magnesium based composites are analyzed.

Based on computer and some relative technologies,the latest progress in missile design technology is discussed,the technologyies include the Multidiscipline Design Optimization(MDO)which is built on information integration,network and database system,the Virtual Product Development(VPD) technology which is validated by Digital Prototype(DP),and the Concurrent Engineering(CE) technology.

Traditional missile design procedure cannot achieve synergic design of subsystems well.

With the development of missile weapon in high-tech local wars in the future,higher performance,lower cost,and shorter lifecycle have become new requirements for missile design.
