Echo power spectrum
Bistatic CCN/RT-13 continuous wave echo power spectra of the lunar surface obtained at Svetloe and Zelenchukskaya observatories on August 13, 2020 from 08:40:01 to 08:40:06 UT. Solid and dashed lines denote echo power in the opposite circular (OC) and same circular (SC) polarizations as that of the transmitted wave.
