Zusammenfassung:	An in-service radar detection unit for a wireless analog video receiver includes a channel estimator, a signal recovery vector creator, a signal estimator, a radar detector, and a control transmitter. The channel estimator generates a channel estimation between a transmitter and a receiver from a plurality of signals received on a plurality of antennas. The signal recovery vector creator creates a non-zero nulling vector from the channel estimation. The signal estimator utilizes the nulling vector to restore an additional signal, other than an analog video, from the received signals. The radar detector detects a radar signal in the additional signal, and the control transmitter transmits an indication of the detected radar signal using at least one of the antennas.
