摘要
激光测距方程的表达形式与目标反射模型的选取有关。不同文献中的测距方程不尽相同,通过对不同反射模型测距方程的推导,指出不同文献中测距方程的联系及测距方程差异产生的原因。用数值模拟的方法,直观给出不同目标模型回波信号的差别及其强度随探测距离、仰角的变化关系。在设计脉冲激光测距仪时,模拟结果可以帮助选取合适的参数。
The laser ranging function depends on the reflection model of object,generally,there are some differences of it in different papers. The relationships among the different laser ranging functions and the causations which lead to the differences are obtained by using different reflection models of object. The depen- dence of returned power on the distance with different laser ranging functions and different elevations are revealed intuitively by utilizing numerical simulation. When the pulsed laser ranging finder is designed,the numerical results will be helpful for choosing the parameters of it.
