Claim 0:
1. A radar sensing system comprising:
a transmitter configured to transmit radio signals; and
a receiver configured to receive radio signals that include (i) the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment, and (ii) interfering radio signals transmitted by another radar sensing system;
wherein the receiver comprises an interference canceller configured to mitigate the interfering radio signals received by the receiver, such that the receiver can estimate a location of an object; and
wherein the interference canceller comprises a linear frequency modulation canceller comprising a finite impulse response (FIR) filter configured to output a linear prediction, wherein the prediction is subtracted from an FIR input signal to generate an error signal that drives the prediction, and wherein the linear frequency modulation canceller generates the canceller output.
