摘要：
Acoustic heterodyne radars use accurately surveyed or otherwise known locations to repetitively launch at least two, intense acoustic tone soundwaves (F1, F2) into an underground area of search. An acoustic receiver is tuned to receive either the sum (F1+F2) or difference (|F1−F2|) heterodynes and is configured to measure and log the overall relative attenuation and roundtrip travel times of the soundwaves, like a typical radar. Any acoustic heterodynes received are assumed to be the work of non-linearities and stresses in the search area. A full-waveform three dimensional tomography algorithm is applied by a graphics processor to the collected and logged data to generate maps and profiles of objects beneath the ground which are interpreted to have produced the acoustic heterodynes.
摘要（中）：
声学外差雷达使用精确测量或其他已知位置重复地发射至少两个强烈的声音声波（F1，F2）到地下搜索区域。 声学接收机被调谐以接收和（F1 + F2）或差分（| F1-F2 |）外差，并被配置为测量和记录声波的总体相对衰减和往返行进时间，如典型的雷达。 接收的任何声学外差被认为是搜索区域中的非线性和应力的工作。 全波形三维断层摄影算法由图形处理器应用于收集和记录的数据，以生成被解释为产生声学外差的地面下的物体的地图和轮廓。
