This will then allow for new radar, video pulses, generated by a spark gap. The OFDM radar system has only been performance verified for a single user and since Doppler measurement is not easily repeatable, it is thus unreliable to use measurement verification for performance observation purposes of a real scenario. The handling of the radio channel is an important aspect that determines the working capability of a mobile communication system. The use of the effective aperture of a sparse multistatic array reduces the number of required transmitters (T x ) and receivers (R x ) and preservers the array's imaging quality ( Lockwood et al., 1996).
