Electromagnetic railgun in-bore velocity measurement with microwave Doppler radar

摘要: 介绍了W波段多普勒雷达测量电磁轨道炮内弹道度速度的基本方法,并对口径30 mm25 mm的串联增强型电磁轨道炮内弹道速度进行了实际测量。初步研究表明:雷达接收的信号易受到脉冲放电过程的干扰;雷达信号的信噪比取决于电枢与轨道电接触状态,在电源充电电压较低、接触面无电弧生成时测得了完整的内弹道速度,并与丝网靶和磁探针测量结果吻合;在较高充电电压条件下,由于电弧电接触产生的干扰,测速结果不够理想。Abstract: This paper describes the preliminary experiments of measuring the in-bore velocity in 30 mm 25 mm caliber augmented railgun with W-band Doppler radar. The results indicate that the radar signals are strongly affected by pulsed magnetic field and armature-rail electrical contact. At low charging voltage, no arc generated between contact surfaces and the whole in-bore velocity was obtained; while at higher charging voltage, due to the generation of electrical arcs, the radar signal was attenuated too much and the velocity results was poor.
