Patent ID: 7969350

Claim:
A method for reducing a leakage component of a received-signal performed by a radar system having a transmit antenna and a receive antenna, the method comprising: transmitting a first transmit-signal via the transmit antenna, wherein the first transmit-signal includes a first transmit component, and wherein the first transmit component includes a first pulsed signal and a first transmit component leading edge that corresponds to a first transmit time; receiving a first received-signal via the receive antenna, wherein the first received-signal includes a first leakage component and a first target component, wherein the first target component includes a first target component leading edge that corresponds to a first receive time, and wherein the first received-signal corresponds to the first transmit-signal; determining a time difference between the first receive time and the first transmit time; determining whether the time difference between the first receive time and the first transmit time is greater than a first amount of time; and when the time difference between the first receive time and the first transmit time is greater than the first amount of time, producing an estimate of the first leakage component, and responsively producing a reduction leakage component based, at least in part, on the estimate of the first leakage component.
