Abstract:

This handbook is intended as a primer for people involved in ship architecture and design but who are not necessarily familiar with radar detectability factors. Its scope is therefore broad, but its depth is limited. Methods for reducing radar ship echo are described and demonstrated. Modern surface ships are far from optimum shapes from the radar echo standpoint. They typically have many flat horizontal and vertical surfaces meeting at right angles, all of which constitute strong radar reflectors. Major improvements reductions in detectability can be made using a few simple techniques 1 replacing flat surfaces with curved surfaces 2 tilting upright surfaces away from the vertical 3 angling flat surfaces at other than 90 degrees 4 using screens and 5 installing radar absorbent materials. Although these concepts are simple, we realize that incorporating them in ship design is not so simple. Each imposes its own brand of penalty, not the least of which is cost. Nevertheless, if detectability is to be reduced, the penalties must be paid.
