impact noise ratio的意思|示意

Under the impact of a large hammer, a high signal noise ratio of the force and velocity can be acquired in the high-strain dynamic testing.

高应变动力试桩法采用数吨重锤锤击，同时实测了桩顶的力信号和速度信号，具有很高的信噪比。

The results show that when the millimeter wave radar has the short-distance detection, signal-to-clutter ratio is more than signal-to-noise ratio. So rainfall is an important impact factor.

结果表明：在毫米波雷达近距离探测时，信杂比大于信噪比，雨杂波是重要的影响因素。
