弹丸对雷达隐身的技术

Technology of a Radar Stealth Projectile

为了实现弹丸对炮位侦察校射雷达隐身,研究了弹丸对雷达隐身的原理和结构,采用改进弹丸表面和形状的技术,实现弹丸外形隐身,研制S波段、X波段窄带吸波材料,涂覆在弹丸表面上,实现弹丸窄带吸波材料隐身,测试了隐身弹丸的雷达散射截面及其对雷达的隐身效果,结果表明:与传统的杀爆弹相比,隐身弹丸的雷达散射截面明显减小,被雷达探测到的距离显著缩短,弹丸具备了隐身性能。

In order to develop a stealth projectile to antagonism hostel side artillery fire finder radar, the principle and structure of a radar stealth projectile are researched. Using improved surface and shape, a projectile get shape stealth. Narrow band radar absorbing materials for S-wave-band and X-wave-band are developed. As narrow band materials are coated on projectiles surface, the projectiles get material stealth. The radar cross section and performance of the stealth projectile are measured. The experiment result shows that, compared with traditional explosive bomb, the stealth projectile radar cross section is decreased explicitly, the distance of being find by radar is very shorter. The projectiles have gotten stealth performance significantly.
