    en.wikipedia.org/wiki/Ground-penetrating_radar

    Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [ 1 ]

    en.wikipedia.org/wiki/RIMFAX

    The Radar Imager for Mars' subsurface experiment (RIMFAX) is a ground-penetrating radar on NASA's Perseverance rover, part of the Mars 2020 mission. It uses radar waves to see geologic features under the surface. The device can make detections dozens of meters/yards underneath ground, such as for buried sand dunes or lava feature. [1]

    At the time, the railSAR fell into the highest category of UWB radar systems, operating across a 950 MHz-wide band from 40 MHz to 1 GHz on a pulse strength of 2.5 megawatts. [1] [3] [4] It provided fully polarimetric, high resolution radar data and possessed 185% bandwidth compared to other radar systems that had less than 25% bandwidth. [1] [5]

    The frequency range for this type of ground penetrating radar equipment is 10-2300 MHz with a peak frequency between 100 and 1000 MHz and pulse duration of 0.2 to 4.0 ns. More than 50,000 lineal feet of data can be collected and stored in the US Radar unit before being transferred via USB port to a Windows-based operating system that processes ...
