AWR1843AOPEVM: Does the sensor have enough penetration power to see 50cm inside the ground?

Part Number: AWR1843AOPEVM

Hello Experts,

I am designing a ground penetrating radar system that I am going to hold at about 1 meter over the ground distance. I only need to see 0.5 meter depths with 0.05 meter range resolution. Would anyone happen to know if the generated signal from AWR1843AOPEVM has enough power to penetrate 0.5 meters into the ground? The second object inside the ground is going to be metallic and the ground is just dry soil so I assume that relative permittivity is going to be differing enough.  If not is there any other sensor that could give me such penetration power?

Any help or an advice would be highly appreciated.

Thank you

    Hello,

        It would be hard to detect object at 0.5m under the ground, There would be lot of reflection at the ground surface itself, within few centimeters mmWave signal would get severely attenuated based on the soil density. Typically ground penetrating radars use lower frequency, because of frequency-dependent attenuation mechanisms, higher frequencies do not penetrate as far as lower frequencies. Hence most of ground penetrating radar system uses less than 10GHz frequency. 

    Thanks and regards,
