巡飞弹对地物金属目标的毫米波探测

Ground Metal Target Detection Based on Scout Missile of Millimeter-wave Radiometer

对地物表面运动金属目标的有效探测是实现精确打击的重要保障。根据地物表面运动金属目标的毫米波辐射特性，建立了基于毫米波辐射计的巡飞弹对地物金属目标的毫米波探测数学模型。通过改变巡飞弹飞行参数，对该数学模型进行了数值仿真，结果表明：巡飞弹的有效旋转速度为30～70rad／s，有效采样时间为0．1105～0．275ms，有效飞行高度为17～28m时，可实现对金属目标的有效探测。

To detect the ground metal target effectively is an important guarantee for preci- sion strike. Accordingly and in view of the millimeter-wave radiation characteristic of the ground metal target, a mathematical model was established based on Scout Missile about millimeter-wave detection to the ground metal target. Through changing parameters in the process of Scout Missile flight, the model goes on numerical simulation, the results show that：effective rotation speed of scout missile patrol is 30-70rad/s, effective sampling time is 0. 1105 ~ 0. 275ms ,effective flight altitude is 17 -28m, which is to achieve effective de- tection for the metal target.
