Targets:
The shape of the target has a direct affect on the image displayed.
A flat surface at right angles reflects a good image. Flat surfaces at
shallow angles reflect very poor images. A concave surface will
concentrate the reflective energy and display an image larger than
normal. Convex surfaces will scatter the energy and display week
images. A conical surface may not display any image.
The texture of the target surface also controls the amount of reflective
signal, and therefore the image displayed. A smooth surface is a good
reflector, while rough surfaces tend to break up the reflection.
Composition - materials such as metal and water are good reflectors.
Others, such as wood and fiberglass are poor reflectors.
