Claim:
1. A method for providing interference rejection, the method comprising: receiving an interference signal from a source positioned outside a monitored region; receiving a composite signal transmitted from a tagged object moving about a playing field within the monitored region, wherein the composite signal comprises a location signal and a component of the interference signal; detecting whether the component of the interference signal exceeds a threshold value; adjusting, via a processor, filtering of the composite signal to attenuate the component of the interference signal based on the detecting whether the component of the interference signal exceeds the threshold value; causing a directional receive antenna to be directed toward the monitored region, the directional receive antenna operable to receive the composite signal; causing a second sampling antenna to be directed away from the monitored region, the second sampling antenna operable to receive the interference signal; determining a first ratio of a signal strength of the interference signal to a ultra-wideband signal received by the second sampling antenna; causing the interference signal and the ultra-wideband signal received by the second sampling antenna to be summed in an instance in which the first ratio is greater than a second ratio of a signal strength of the interference signal to a ultra-wideband signal received by the directional receive antenna; and combining, using a combiner, the composite signal with the summed interference signal and the ultra-wideband signal to enable cancellation of the interference signal.
