Systems and methods for networking detection devices associated with police activity are provided in a network that includes at least one server (180) and a number of client devices (130-150). Each of the client devices (130-150) transmits its location information to the server for storage. When a client device (130) receives detection information relating to radar activity, a police sighting or other police activity, that client device transmits the detection information to the server (180). The server (180) may then transmit the detection information to other client devices (140,150).

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.

One application described is detecting tool wear using a microwave Doppler-based acoustic emission sensor and predicting tool wear based on the detected acoustic emission.

A radar detector includes features to reduce emissions such as those typically generated by the detector's local oscillator. Two low noise amplifiers (LNA's), operating in X band and a combined K / Ka band, respectively amplify X and K / Ka band signals from separate antennae, and deliver those signals over separate, elongated and narrow signal paths to X and K / Ka mixers, where those signals are mixed with local oscillator (LO) signals to produce IF for detection. The elongated, narrow signal paths from the antennae to the mixers reduce LO emissions, and those emissions are further reduced by incorporating radar absorbers between the circuit board and detector case along the antenna-mixer path, including radar absorptive paint on the circuit board itself along this path, and sealing the case with a conductive sealing gasket.
