摘　　要：持枪机器人是安装了枪械的无人武器平台。使用者在远处操纵射击,在监视屏上瞄准目标。由于图像传输需要时间,具有100-300 ms的延迟。为了研究使用持枪机器人过程中,延迟对于跑动目标命中率的影响,建立了在平坦开阔地带,目标（敌方士兵）不被击中的临界速度的计算式。并对于不同的延迟时间,计算了目标以不同方向跑动时,逃脱的临界速度。分析计算结果表明：安装了步枪或手枪的无人武器平台,若有150 ms以上的延迟,目标跑动方向和子弹轨迹有15°以上的夹角,只要目标不太慢,很容易逃脱。因此瞄准时需要加以修正。Gun robots are unmanned weapon platforms with guns. Users operate them at a distance and aim target on screen of control box. Because image transmission needs time,the images would be delayed of 100 - 300 ms. To study the influence of the delay to hitting probability of shooting running targets in flat open land,we established a formula of critical speed that enemy soldiers can be shot. It calculated,for different image delay time,various critical speeds of the targets running in different directions. Based on the calculation results,we can conclude that as long as the targets are not too slow it is very easy for them to escape the shoot if the unmanned gun platforms with rifle or pistol have delay above 150 ms,and if angle between targets running direction and bullet track excesses 15° or above 15°. Thus the aiming method of the robots should be improved.
