Abstract: (Draft of full paper is attached)
Because the SDR has both an RF transmitter and a receiver integrated in the same module, leakage from transmit into receive path is inevitable. Without proper compensation, the received radar signal is combined with this unintentional leakage signal from the transmit path creating unintended distortion in phase and amplitude. This type of accuracy...
