摘要： An apparatus for detecting a traffic participant includes a first detection device for detecting the traffic participant in a first detection zone. The first detection device is configured to repeatedly detect the first detection zone and to detect an entering of a traffic participant in the first detection zone, and/or to detect the traffic participant in an angular section in an extended first detection zone beyond the first detection zone according to an instruction. The apparatus also includes a second detection device that detects the traffic participant in a second detection zone, and is adapted to provide data required for instruction about the traffic participant in response to the detection of the traffic participant and to forward it to the first detection device for instruction. This way, the traffic participant may be detected by the first detection device before entering the first detection zone.

The steps of identifying a location of each legacy radar unit, setting a threshold altitude, and determining a legacy occultation of each legacy radar unit from a landscape level up to the threshold altitude are also disclosed. Mapping the legacy occultation of the legacy radar units to provide a three dimensional occultation map in the defined area and locating gaps below the threshold altitude in the legacy radar coverage as a function of the occultation map are also disclosed. Identifying a plurality of sites as a function of the gaps where the sites are accessible to receive a radar unit is also disclosed. Determining an anticipated radar coverage of a radar unit positioned at each of the sites and determining a reduction in the gaps as a function of the anticipated radar coverage are also disclosed. Selecting sites as a function of the reduced gaps is also disclosed. X band, C band or S band radar units can be positioned at the selected sites. The threshold altitude can be 10,000 or 15,000 feet. Affected populations and costs can also be considered in radar placement.

摘要： A rotating wheel of a vehicle is detected by evaluating the Doppler shift of a measuring beam, which is emitted by a detector unit passed by the vehicle, and is reflected by the wheel and returned in Doppler-shifted form. In a relative position to the wheel, the vehicle comprises an onboard unit, which can establish radio communication with a transceiver having a known location in the detector unit. The direction and distance of the onboard unit from the transceiver are measured on the basis of at least one radio communication between the same. The radiation direction or radiation position of the measuring beam is controlled in accordance with the measured direction and distance and taking into consideration the aforementioned relative position and location.

摘要： A method and system for communicating using pulsed radar signal data links is disclosed. The method comprises encoding downlink data with a signature sequence as a secondary function onto a continuous wave pulse signal having a primary function at a master device. The data-encoded pulse signal from the master device is interpreted at one or more slave devices configured to receive the pulse signal within a first communications bandwidth of the primary and secondary functions. The master device synchronizes returning communication transmissions from each of the one or more slave devices for the secondary function within a prescribed return interval of the primary function.
