基于贝塞尔滤波器的回波信号提取的仿真和实现

Simulation and Realization of the fidelity of the signal of Laser Altimeter Based on Bessel filter

激光测高仪的回波信号中包含着目标物的粗糙度、倾斜度、反射率等信息,对于复杂地物特征的回波信号,采用多通道匹配滤波技术不仅可以获得高的信噪比,还可以保证信号的保真度。

The laser altimeter contains the information of target such as harshness, gradient, reflectivity and etc.The multichannel matching filter technique is used to automatically acquire best signal-to-noise ratio from different targets and to ensure.
