摘要
依据激光测量系统的设计、评价需要,对目标激光雷达截面(LRCS)的计算方法及应用等有关问题进行了研究。在讨论LRCS一般计算方法的基础上,重点针对镜面反射目标,提出了一种简便的LRCS工程估算方法,并应用于激光角反射器目标和“猫眼”目标,得到了相应的LRCS估算公式;从目标LRCS的角度推导出激光测量方程,该方程可普遍适用于各类激光测量系统和各种散射特性目标,并具有应用简单、方便的特点,可广泛应用于各类激光测量系统的论证设计和性能评价。
Several problems about the calculation and application of laser radar cross section （LRCS） for targets were investigated. The general method for calculating LRCS was derived and discussed. A very simple method for calculating the LRCS for direct reflection targets was proposed and applied to the optical comer reflector and ＂cat-eye＂ target respectively, with the formulas for estimating their LRCS. The general laser measure equation applied to various laser measure systems and targets was derived in terms of LRCS. The equation is simple, applicable and can be applied in the design and evaluation of various laser measure systems.
