摘要
推导用远场分布不均匀的激光进行测距的测距方程。给出面积小于光束横截面时发射机的有效束宽角概念,并用此概念解释对小目标进行跟踪测距时,命中概率随着距离增加而下降的趋势。给出了在测距总体上提高命中概率、计算发射机功率的具体步骤。
A rangefinding equation for laser non-uniform far-field distribution is derivedarid the effective beamwidth angle concept of transmitter is given for the case offarget area which is smaller than beam cross section,and this concept is used toexplain the tendency of hit probability decreasing with the increase in the rangein the case of tracking and rangefinding small target.The steps of increasingthe hil probability and calculating the power of transmitter are given.
