抛物线用作雷达阵地地面有效反射区曲线

The Curve on Effective Reflection Areaof Radar Position with Parabola

讨论了传统的米波雷达地面有效反射区和粗糙地面的选择条件,提出采用抛物线作为地面反射区曲线,并给出曲线公式,各反射点的反射波在主要方向同相叠加增加了探测距离,进一步挖掘了米波雷达的威力潜力;合理选择反射区曲线的长度,可减少近地物反射的杂波,提高低空目标的探测能力。

This paper discusses the meter wave radar position conditions of the traditional effective reflection area and the coarse ground.It presents a brand new idea that parabola curve is adopted to enhance the covering distance of meter wave radar (the detailed parabola function is presented)by integrating the energy of the reflection on different ground points.Through selecting appropriate curve length of the reflection surface,it can reduce the reflection clutter of the near ground and improve the detection ability of low altitude.
