【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30mm×25mm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。更多还原

【Abstract】 This paper describes the preliminary experiments of measuring the in-bore velocity in 30mm × 25mm 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 inbore 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.更多还原
