文摘：介绍了三种北极浮冰遥感数据的自动处理和分析方法。主要的重点是在1960年冬季SSN 583，SARGO北极巡航期间获得的浮冰底部的上视声纳剖面。研究了两条横贯线，一条在楚科奇海，一条在博福特海。利用功率谱和振幅频率分布技术对剖面分段进行了分析。功率谱分析表明，压力脊的优先间距与明显的周期为20-25，35-40和80-100米。功率谱的两个配置文件相交成直角的比较表明，预期的空间周期转移的重要冰脊合奏，因此建议一个潜在的实时技术，从潜艇巡航淹没，冰脊方向确定。（作者）
Abstract : Automatic processing and analysis of three types of remote sensing data of arctic pack ice are described. The primary emphasis is on upward-looking sonar profiles of the underside of pack ice obtained during the winter 1960 arctic cruise of the SSN 583, SARGO. Two traverses, one in the Chukchi Sea and one in the Beaufort Sea were studied. Segments of the profiles were analyzed by power spectrum and frequency distribution of amplitude techniques. Power spectrum analysis indicated preferred spacing of pressure ridges with apparent periods of 20-25, 35-40 and 80-100 m. Comparison of the power spectra of two profiles intersecting at a right angle showed the expected spatial period shift of significant ice ridge ensembles and so suggests a potential real-time technique for determining, from submarines cruising submerged, ice ridge orientation.
