載した本船１から電波を出して計測していた。2. Description of the Related Art Conventionally, as shown in FIG. 5, the radar effective reflection cross-sectional area of a ship is measured by a radar on land or on a ship. The ship 2 to be measured was separated from the ship 2 by a predetermined distance, and radio waves were emitted from the ship 1 equipped with a radar device for measuring the effective reflection cross-sectional area for measurement.

慮した、計測結果の比較も行うことができなかった。By the way, it is known that the radar effective reflection cross section of a ship changes very sensitively to the incident angle of radio waves, and when measuring the reflection cross section of the ship 2 on the sea, Parameters such as the attitude of the hull and the relative angle with the device are important. However, since there is no measuring device that measures the attitude of the hull at the same time as the radar effective reflection cross-sectional area, it is possible to obtain only a general tendency from the measurement results with large fluctuations. Moreover, it was not possible to compare the measurement results considering the influence of the difference in the attitude of the hull.
