backscattering

基本解释

So, what we want to do now is see if we can understand how this backscattering experiment worked.
希望现在能更简洁一点,好，我们现在,要做的就是看看,我们是否理解了。
But in our case, the probability of backscattering is going to be the number of balls that backscatter, and that's going to be divided by the total number of ping-pong balls.
用20除以132000，但现在背散射,的概率是被散射回来的小球，除以总的小球数,你们记得。
A sensor on the aircraft records the time it takes to receive the backscattering of pulses, and that is used to compute distances to the forest canopy and to the soil beneath.
这架飞机上的一个探测设备记录下它收到脉冲反向散射所需时间而且这个时间可用于计算到森林树冠层和到树冠层下土壤的距离，以此而计算出树干高度。

So, once we figure out what our probability of backscattering is, we'll just raise that to the 1/2, and we'll multiply that by 12 . 20 centimeters.
所以一旦我们,知道了散射概率，我们开根号。

So, what we want to do now is see if we can understand how this backscattering experiment worked. So we will do our own backscattering experiment.
希望现在能更简洁一点,好，我们现在,要做的就是看看,我们是否理解了。

All right. So now all we have to do is figure out this probability of backscattering.
在乘以12。20厘米,好，现在只要。
