冰，对电磁波来说则是透明的，会把原来的左旋极化波反射回来。
Ice, which is transparent to radio waves, also sends back left-polarized waves.
光滑表面会反射一个反向的优选极化波，而粗糙地区的反射波是左旋极化波。
While smooth surfaces send back a reversed, right-polarized wave, rough areas return left-polarized waves.
那个叫做Mini-SAR的雷达，通过向月表发射左旋极化电磁脉冲来测定月球的表面粗糙度。
The radar, called the Mini-SAR, sends pulses of left-polarized radio waves out to measure the surface roughness of the moon.
