WISDOM
The Water Ice and Subsurface Deposit Information On Mars (WISDOM) instrument is a ground penetrating radar (GPR) operating in the UHF frequency range from about 500 MHz to 3 GHz with a relatively small radiofrequency (RF) output of 20 dBm.
Two Vivaldi antennas are used for transmission of the pulses and reception of the reflected signals. The electromagnetic waves transmitted by the radar will be reflected on subsurface targets that are formed by inhomogeneities in electrical parameters (permittivity, conductivity). Due to the relatively high frequency a penetration down to several meters can be expected (2 to 3 metres), similar to the depth reached by the Rover drill system for sample acquisition.
The radar uses the stepped frequency synthesis principle. For each emitted frequency the real and imaginary part of the return signal are processed and out of the N frequency responses the transfer function of the subsurface can be derived. With an inverse Fourier transform the synthetic time response of the subsurface can be computed.
