Abstract
A radar system includes a receiver that is capable of attenuating transmitter feedthrough in a receive signal. In some embodiments, a fixed frequency notch filter is used to attenuate feedthrough at an intermediate frequency (IF). In other embodiments, an electronically tunable notch filter is used. Phase compensation may be provided to correct for a phase shift of the notch filter.
