In this experiment, the installation of corner-reflector enabled us, within the practical distance of 4 —5 miles, and under the stress of 4 —5 wind-power, to inspect and search the long-line conditions to prevent its snapping away successfully. The items reported on the first paper was advanced ; with a prospect promising us a safe and secured manipulation, under the darkness of night, without any fear of long-line's snapping away. The further research will be rewarded by an advanced and more practical method of securing the long-line manipulation's stability.}, pages = {53--59}, title = {レーダーによるマグロ延縄の探知について(第2報)}, volume = {5}, year = {} }
