Abstract
Example embodiments relate to transmitter-receiver leakage suppression in integrated radar systems. One embodiment includes a front-end for a radar system. The front-end includes a transmit path that includes a power amplifier and a transmit antenna. The transmit path is configured to transmit a transmit signal. The front-end also includes a receive path that includes a receive antenna and a low-noise amplifier. The receive path is configured to receive at least a leakage from the transmit path. The receive path is configured to generate an amplified signal of the leakage. Further, the front-end also includes a reference path. In addition, the front-end includes a compensation unit in the reference path. The compensation unit is configured to generate compensation for a leakage path between the transmit path and the receive path. The compensation unit is configured to apply the generated compensation to the reference signal to generate a compensated reference signal.
