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 for alerting an operator of a motor vehicle to an incoming police radar signal. This radar detector includes a microprocessor; a circuit coupled to the microprocessor for detecting the incoming police radar signal; and a global positioning system receiver coupled to the microprocessor. Upon detection of an incoming radar signal, the radar detector can utilize the position, velocity, and/or heading data from the global positioning system receiver to determine whether to generate an alert.

Wireless and other external connectivity technology is used in various ways to enhance or improve upon existing radar detector and police activity detection systems. External memory interfaces, such as SD cards or USB, provide external storage. Wireless interfaces such as Bluetooth, Zigbee, 802.11, and wireless personal area network communication protocols, allow a detector processor to interact wirelessly with external devices, such as a Bluetooth headset, a cellular network device providing a server connection, or toggle buttons used to indicate the presence of police activity at a current position. Further, radar detectors are upgraded to provide GPS capabilities, using the existing power/data connector of the radar detector.

Acoustic emissions are detected by reflecting microwave radar signals off of an object, receiving reflected radar signals, generating an intermediate frequency, and filtering the intermediate frequency to remove low frequency signals associated with object movement and not acoustic emissions. A microwave Doppler radar detector provides the signals, a band-pass filter filters the intermediate frequency signal, and resulting signal is collected and analyzed to establish a relationship between the acoustic emission and the filtered signal. 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.

The invention relates to a method and a device of railway roadblock detection and alarm based on radar return characteristics. When a train drives at a high speed, a radar detector abstracts the radar return characteristics of the front road surface in real time. According to information of the train position supplied by a global position system (GPS) inertial navigation system, a data processing and display and control and warning platform reads previous echo characteristic statistical data of the train at safe driving from a memorizer, and compares the train position information with the previous echo characteristic statistical data. If the echo characteristics have abnormal fluctuation, a system can send out a warning signal, and sufficient processing time is supplied to a driver on the premise of guarantee of a safe brake distance. A millimeter-wave radar related in the railway roadblock detection and alarm device is long in detection distance, and high in resolution ratio, can obtain information of the front road surface through real-time processing of the signals, can not be affected by weather and climate, is simple an practical in system, and can meet requirements for roadblock detection.

A GPS enabled radar detector dynamically handles radar sources based upon previously stored geographically referenced information on such sources and data from the GPS receiver. The detector includes technology for determining the location of the detector, and comparing this location to the locations of known stationary sources, to improve the handling of such detections. The detector may ignore detections received in an area known to contain a stationary source, or may only ignore specific frequencies or may handle frequencies differently based upon historic trends of spurious police radar signals at each frequency. Notification of the driver will take on a variety of forms depending on the stored information, current operating modes, and vehicle speed.

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.
