NAME RADAR IMAGER FOR MARS SUBSURFACE EXPERIMENT (RIMFAX)
TYPE
DESCRIPTION 
RIMFAX is a ground penetrating radar that uses a single antenna to transmit 
            (via a transmitter, TX) and receive (via a receiver, RX) electromagnetic waves 
            over a range of frequencies (150 to 1200 MHz) into/from the surface.  
            The instrument can be operated in either active (TX and RX) or passive 
            (RX-only) modes. Transmitted waves propagate downward until they are 
            reflected back by the surface and shallow interfaces in the subsurface 
            geologic structure across which discontinuities in permittivity (i.e., 
            storage of electrical energy in an electric field) exist.
