摘要
为提高激光遥感探测测距性能,研究了倾斜地面回波波形对测距精度的影响。介绍了激光回波脉冲的数学表达式,并基于此研究了斜坡地形目标的激光回波波形及其展宽情况,通过仿真分析了前沿阈值鉴别法、恒比定时鉴别法和质心鉴别法对斜坡地形测距的误差性能,结果表明质心鉴别法的测距误差性能较好。
The impact of the waveforms of return signal from slope terrains on ranging precision was studied to improve the ranging performance. The expression of laser echo was introduced and then based on it the echo stretch of slope terrain was discussed. The ranging performances of threshold method, CFD and waveform centroidal, method were analyzed, the results indicate that waveform centroidal method is the most available.
