测距机对缓慢运动的目标测距与雷达连续测距的方式是不同的,其特点是,测距是断续的且不等间隔(几秒内),即测距机测手测准目标后才把距离量传出,至于何时测准取决于目标位置的变化和测手的熟练程度。此时目标方位量仍连续输入。在此种方式的情况下数字机求取目标运动参数,不能直接采用一般等间隔的数字平滑公式,必须作某种处理。采用此方法的基本点是把输入不等间隔的距离d作一次或二
Ranging machine for slow motion of the target range and radar continuous ranging approach is different, which is characterized by ranging is intermittent and not at an interval (within seconds), that is, After the amount of distance came, as to when the calibration depends on the target position changes and the skill of the hand. At this point the target position is still continuous input. In this way the digital machine to obtain the target motion parameters, can not directly use the general equal-interval digital smoothing formula, must be for some treatment. The basic point of using this method is to input the unequal spacing distance d once or twice
