Radar is an indispensible equipment in all vessels under way. In Korea there are many fishing net buoys near the coast, which causes an enormous threat to safe navigation because it is very difficult to detect the buoys by radar due to their small radar cross section. In this study RTE(Radar Target Enhancer) was installed on the fishing net buoy and its echo was analysed carefully. The results showed the possibility of wide detection of targets, especially small targets such as fishing net buoys, navigation buoys and etc.
