以雷达对海面目标进行观测为例，当擦海角（入射余角）接近90°时，海面的散射系数σ0会增大到+10dB左右，此时回波距离像中目标将被杂波完全淹没。

As airborne radar observes targets on the sea surface at high grazing angle approaching 90 °, scatter coefficient σ 0 becomes so great ( around + 10dB ) that targets will be completely submerged by sea clutter in the range profiles of echoes .
