在激光引信脉冲宽度较宽时，激光测距容易因起始脉冲间的时间间隔无法判别而产生误差。本文提出一种新的激光引信距离测量方法，即通过实时检测回波形心位置来完成对发射脉冲和返回脉冲信号延迟时间的测量，进而求得目标距离。在激光引信系统中应用此方法进行测距试验，结果表明该方法实现了0 k．5m的定距精度，有效地提高了激光引信系统定距的精度，满足实际需要。

During the laser ranging , the error caused by time-interval measurement error can produce when the pulse width of laser fuze is too wide .So a new range finder method for pulse laser fuze is pro-posed.The method is first measuring the delay time of transmitted pulse signal and return pulse signal through real-time detecting the center of echo waveform , and then calculating the target range with it .Ap-pling this method a series of range experiments are proceeded , the experimental data are given and the er-ror is analyzed in theory .The results show that the precision of 0 .5 m level is achieved and the ranging precision of the laser fuze is improved , which meets the practical needs .
