小型船舶等の電子的視認性の向上に関する基礎研究

摘要

To decrease collision disaster, authors examined early detecting of small boats with the enhancement of an Electrical Visualization.rnMost small boats are made by FRP, but there is few observation on its radar cross section. The authors measured Radar Cross Section (RCS) of small boats. As results, RCS of boats of less than 5 G/T was 6 m and RCS of bigger boats was 15 m. The RCS is not so small, however in actually, it is difficult to detect these small boats by radar. The authors thought that it was difficult to detect small boats even if small radar reflector was installed for them, because big radar reflector is not suitable for them.rnSo the authors make a proposal of a radar transponder operating at out-band of radar frequency band with small output power using solar power cell, communication system and network.%FRP 船のレーダ断面積を実測したレーダ受信電力より求め、5トン未満では約6m~2、5トン以上では15m~2であることがわかった。結果として、レーダレフレクタのみによる電子的視認性の向上は効果が低いことがわかり、その他の方法について調査?検討した。
