半隐身弹丸对雷达的隐身性能研究

Research on the Stealth Performance of Half-stealth Projectile against Radar

为了实现弹丸对炮位侦察校射雷达隐身的目的,研究弹丸对雷达隐身的技术,在弹丸外形隐身的设计上采取全隐身和半隐身两种结构方式。全隐身弹丸是完全依据外形隐身设计规范而设计的,其结构为次口径碟形隐身弹丸,虽然其隐身效果突出,但牺牲了弹丸威力和精度。为了在保持弹丸威力和精度前提下实现雷达隐身的目的,采用全膛隐身弹丸结构,弹丸前定心部表面不涂覆吸波材料、直接接触炮膛,成为半隐身弹丸。设计制造X波段、S波段半隐身弹丸,并在试验中利用炮位侦察校射雷达搜索、跟踪半隐身弹丸,检验半隐身弹丸对雷达的隐身效果,试验结果证明半隐身弹丸的确具备隐身性能。

The stealth technology of projectile is researched to develop a stealth projectile to counter hostile artillery locating and fire correction radar. The contour stealth design of projectile includes full-stealth and half-stealth structures. The full-stealth projectile structure is designed according to the full-stealthy design specifications. The full-stealth projectile is a subcaliber disc-type projectile. The full-stealth projectile has emarkable stealth performance,but it has the reduced power and hit accuracy. So a full-caliber stealth projectile structure is designed. The front bourrelet of projectile is not coated with radar absorbing materials and touches the bore directly to form a half-stealth projectile. The X and S band halfstealth projectiles were designed and manufactured. The half-stealth projectiles were searched and tracked by using an artillery locating and fire correction radar. Experimental results show that the half-stealth projectile has stealth performance.
