摘要
由于连发时群目标分辨及高速启动技术难题,高射速火炮弹丸初速测量一直是一个难点。文中采用基于距离分辨的时间—距离—频率分辨的方法来区分多目标,满足了高射速火炮连发时的群目标分辨要求;采用红外触发结合微波触发方式,用微波信号发生器照射炮口,当炮弹出膛后,接收到的多普勒回波产生突变,对突变进行检测,获得弹丸的出膛时刻,克服炮口连续火焰的影响。最后,给出了初速测量样机示意图,对以后高射速连发弹丸初速测量的总体设计提供参考。
In view of unresolved targets and high-speed start technology during ripple fire, muzzle velocity measurement is still difficult. The time-distance-frequency method based on the distinguishment of distance was used to distinguish multi-objective in this article. It can meed the unresolved targets demand for ripple fire. Infrared trigger combined with microwave trigger mode was used in this article. Contin- uous wave radar was used to designate muzzle, when projectile was ejected from muzzle, the received Doppler radar echo signal had a mu- tation. When detecting and locating the mutation signal, the time when the projectile leaving from muzzle was got. It can overcome the effect of flame noise. In the end , prototype schematic was given. It can provide the references for the final design for muzzle velocity test of ripple fired projectiles.
