RADIO WITH OOBE VICTIM DETECTION
First Claim
1. A radio for exchanging information with one or more other radios comprising:
- an operating transmitter configured to transmit an operating channel radio transmission from one or more transmit antennas, each of the one or more transmit antenna responsive to at least an operating frequency band; and
a victim-signal detector configured to detect one or more candidate victim RF signals at one or more detection antennas, each of the one or more detection antennas responsive to at least a victim frequency band;
wherein the victim-signal detector is further configured to indicate at least if a level of detection for one or more candidate victim RF signals exceeds a threshold;
wherein the operating transmitter is further configured to utilize a first set of operational parameters corresponding to a first level of out of band emissions (OOBE) for the operating channel radio transmission if the level of detection for one or more candidate victim RF signals exceeds the threshold;
wherein the operating transmitter is further configured to utilize a second set of operational parameters corresponding to a second level of out of band emissions (OOBE) for the operating channel radio transmission if the level of detection for one or more candidate victim RF signals does not exceed the threshold; and
wherein the first level of out of band emissions (OOBE) is lower than the second level of out of band emissions (OOBE).

Abstract
A radar detector is used with a radio link, the radio link characterized by high duty factor operation of a radio transmitter. The radar detector is located a sufficient distance from the radio transmitter that the radar detector is not overwhelmed by the radio transmission signal in that channel and can detect sufficiently low level radar signals to ascertain potential radio interference at the radar from said radio transmitter. The results of the radar detection are communicated to the transmitter in a way that impacts the transmitter'"'"'s use of the sensed channel. This communication can occur reactively when a radar detection is achieved (the absence of which indicates no radar has been detected) and/or can be a periodic or event-driven indication that the channel is available for operation (the information expiring if the result is not refreshed). A highly sensitive radar detector apparatus that can detect wideband radar signals at very low levels and overcome the disparity of detection range versus interference range is described. A signal detector is also described that detects energy from other users that is not in the operating channel or operating band of the transmitter to determine if the out of band emissions or out of channel emissions of the operating transmitter'"'"'s signal need to be adjusted through such settings as transmit power, operating channel, filtering, or a combination.
