Multistatic MIMO OFDM Radar

OFDM signals are well suited for passive and active multistatic radar systems due to their constant carrier frequency and thus relaxed efforts for frequency synchronization in comparison to FMCW based signals. Furthermore, frequency and time shifts can be corrected to a certain degree during signal processing. Active multistatic radar systems additionally offer the advantage that the transmit signal and the position of the transmitter are known and can be arbitrarily controlled. In combination with MIMO such systems could be used to detect small objects with a highly angular dependent radar cross section like drones as well as to relax the demands for decoupling of transmitters and receivers.
