| 内容記述 | It is difficult to detect smal FRP boats on the radar Screen at a greater distance since the Radar Cross Section (RCS) of these boats is so low. Therefore, it is recommended that the Small FRP boat equips with a type approved radar reflector. A large number of theoretical studies have been made on radar reflector. However, at the actual sea area, the quantitative effects with the radar reflentor on the boat are not yet clear enough. In this paper, authors examine the characteristics of radar signal intensity and ecor paint from a small FRP boat which the radar reflector is installed or not in the situation of two aspect angles, these are 90° and 0°. The major results are as follows. (1) The signal intensity on echoes fluctuate 20 dB and more. (2) In the situation without reflector, the RCS (Radar Cross Section) of bow-aspect is less than half that of abeam-aspect. (3) By installing the radar reflector, the RCS increases more than twice as the amount as without reflector. (4) The echo paint characteristics which are size and shape are independent of aspect angle of the boat. (5) Echo size (the bearing size and the range size) of the situation with reflector are bigger than that of the situation without reflector. |
