6.2  STRENGTH OF REFLECTION FROM THE 
TARGET 
 
The signal intensity reflected from a target depends not only on the height and size of the target but also on its 
material and shape.    The echo intensity from a higher and larger target is not always higher in general. 
In particular, the echo from a coast line is affected by the geographic conditions of the coast. 
If the coast has a very gentle slop, the echo from a mountain of the inland appears on the radar display. 
Therefore, the distance to the coast line should be measured carefully.
