Ground-penetrating radar was such an exciting piece of tech—all the surrounding Researchers naturally got excited after hearing about it. The questions appeared in their heads, and although they didn't say them aloud, were also written on their faces.
But then I remembered two important things, and my shoulders fell.
"Except I have no idea exactly how ground-penetrating radar works… Does it have stronger waves? Or higher-frequency waves? Hell if I know. And of course, it must receive them and calculate vectors from which they came to make a picture. Like an ordinary radar. So it at least needs some computational tech… This isn't as simple as a straightforward signal-to-sound interpretation!"
Researchina tilted her head to the side. Despite my words, she didn't look less excited. Only thoughtful—just like other Researchers.
"So 'radar' is a technology that imitates the way some night-flying dragons use to navigate? The 'echolocation' I heard about from Tabletina?"
