近年来，在两个完全不同的研究领域中观察到的现象使人们提出这样一种建议，即无线电波可以在冷冰块中传播，吸收损失很小，可以测量厚度，并且可以通过雷达获得有关底部表面性质的一些信息。本文首先介绍了美国陆军信号研究与发展实验室在极地飞行的飞机携带的无线电高度计（离地间隙指示器）上发现的伪回波所引起的一些工作。之后，它回顾了斯科特极地研究所的工作，在那里，一些在南极运行的IGY电离层探空仪上的意外现象导致了一种专门测量冰厚的无线电仪器的发展。
In recent years, phenomena observed in two quite separate fields of study have led to the suggestion that radio waves may propagate through cold ice masses with sufficiently small loss by absorption to permit the thickness to be measured, and some information about the nature of the bottom surface to be derived by radar. This article describes first some work by the United States Army Signal Research and Development Laboratory arising out of spurious echoes noticed on radio altimeters (ground clearance indicators) carried by aircraft flying in the polar regions. Afterwards it reviews work at the Scott Polar Research Institute where unexpected phenomena on some IGY ionosondes operated in the Antarctic have led to the development of a radio instrument specifically to measure ice thickness.
