Preliminary comparison of 3.5-cm and 12.6-cm wavelength continuous wave observations of Mars [PDF]
Radar observations of Mars at Goldstone in 1990 were conducted by transmitting pure sinusoidal signals at 3.5-cm wavelengths and receiving the Doppler-spread echoes from Mars at Earth. Radar transmissions were circularly polarized and the echoes recorded
