Abstract: An infrastructure-based warning system, where the system is used as part of an intelligent intersection or intelligent road, and is used to detect various objects, such as vulnerable road users (VRUs) and vehicles. The system includes both cameras and radar, the operation of which is optimized based on which of the camera or radar is least affected by current conditions. This optimization includes the use of a marker, attached to infrastructure in the field of view of the detection device, such as a camera, to be optimized. If the camera accurately and consistently detects the marker, then camera detections of objects are weighted with more significance than the detection of objects using radar. If on the other hand, if the camera is unable to accurately detect the marker because of ambient conditions, then the greatest amount of confidence is placed on radar detection.

Abstract: A signal power detection method is fused with a double-difference phase modulation detection method to provide a higher-performance method of pulse detection for any digital receiver. The first pulse detection technique uses a signal power threshold. When the square of the magnitude of a pulse crosses the signal power threshold, the beginning of a pulse is declared and pulse processing starts. The second pulse detection technique is model based and uses a windowed detector that crosses a phase difference threshold when the pulse has consistent second-order (in general d-th order) difference phase values within the window. The first technique has low latency and is independent of pulse width, but only operates well at SNR values greater than 15 dB. The second technique has higher latency and requires a minimum pulse width, but operates at lower (approximately 0 dB) SNR values.

The marked false source location can be used in a detector and/or downloaded to multiple detectors via a social network.

Abstract: A radar detector suppresses alerts from vehicle guidance systems, by sweeping for a consistent radar signal; the center frequency of the signal is stored and the detector suppresses warnings of radar signals near that frequency. The detector uses an enhanced method for suppression of signals near a known location of a false signal source; in the event the detector detects a radar signal and finds a matching stored false signal, the detector will first compare the strength of the received signal to a threshold strength that is computed based upon the distance of the detector from the stored false signal, and will only suppress signals below threshold. The detector includes a camera directed to the road in the vicinity of the vehicle. Image data from the camera is processed to identify police vehicles as identified by flashing lights, a profile including a rooftop light bar and/or highly contrasting colored panels.

Abstract: A signal on a wireless communication system control channel can be identified as authentic or malicious by monitoring control channel signal strength changes. When a control channel signal level increases abnormally, a geographic location is obtained from a navigation system, such as a GPS. The determined location is compared to locations in a data base of locations where control channel jamming transmitters are known to exist, and/or likely to exist. If the then-current location is not in the data base, the detected control channel signal level increase is considered to be malicious, i.e., from a jamming transmitter, often used by car thieves.
