Claim 12:
13. A radar sensing system comprising:
a plurality of transmitters configured to transmit radio signals; and
a plurality of receivers configured to receive radio signals that include (i) the transmitted radio signals transmitted by the plurality of transmitters and reflected from objects in an environment, and (ii) interfering radio signals transmitted by another radar sensing system;
a controller configured to control at least one transmitter of the plurality of transmitters and at least one receiver of the plurality of receivers such that the at least one transmitter and the at least one receiver operate in alternating transmit and receive operational windows, wherein the transmit operational windows and the receive operational windows are separated in time;
wherein a first receiver of the plurality of receivers comprises an interference signal canceller configured to mitigate the interfering radio signals received by the first receiver, such that the first receiver can estimate a location of an object; and
wherein the interference signal canceller comprises a linear frequency modulation canceller comprising a finite impulse response (FIR) filter and is configured as a 1-step linear predictor with least mean squares adaptation, wherein the prediction is subtracted from an FIR input signal to generate an error signal that drives the adaptation, and wherein the linear frequency modulation canceller generates the canceller output.
