3.2 REFLECTION FROM 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, as shown in Fig. 3.2-1. Therefore, the distance to the coast line
should be measured carefully.
