Improvements on multi-input multi-output radar systems

摘要

The present disclosure relates to a method for cancelling spillover in a MIMO radar system. The method comprises transmitting and receiving a signal in a transmit-receive pair (10, 20, 30, 40), the received signal including a spillover signal; routing a part of the transmitted signal of the transmit-receive pair (10, 20, 30, 40) to the received signal to increase the power level of the spillover signal; and cancelling the spillover signal and the part of the transmitted signal by the spillover cancellation subsystem (13, 23, 33, 43) associated with the transmit-receive pair (10, 20, 30, 40). Because the part of the transmitted signal corresponds to the spillover signal both these signal are added together and result in a total signal having a high enough power level to ensure the correct functioning of the spillover cancellation subsystem (13, 23, 33, 43).
