    Abstract: Examples include a system for controlling traffic signalling devices at an intersection, including a first radar sensor that detects road users in a first detection region on a first traffic route, outputting first radar sensor data indicating first sensor detected positions and a first sensor detected radial velocities, and a second radar sensor that detects road users in a second detection region on a second traffic route, outputting second sensor data indicating second sensor detected positions and a second sensor detected velocities. The first radar sensor and second radar sensor are at different locations, or different orientations, or both, and configured such that the first and second detection region have an overlap. An electronic data processing device combines the first radar sensor data and second radar sensor data into combination signals, and controls the traffic signalling devices based at least partially on the combination signals.

    Abstract: The invention relates to a method for determining the distance (R) and relative speed (v) of at least one object remote from an observation point, comprising the following method steps: continuous transmission of at least one first and one second electromagnetic signal in each case of a signal period (Tchirp) from the observation point; the signals consist of signal portions (bursts) having a constant frequency and a predetermined equal duration, wherein the signal portions of a signal cover a predetermined modulation range by means of frequency steps; the signals are transmitted interlaced in that signal portions of the different signals follow one another in time, wherein a frequency hop occurs between the successive signal portions of different signals, receiving the signals reflected by the object as an echo signal and carrying out a mixed operation with the transmission signal for transformation of the received signal into the baseband in a common analog channel; carrying out an analog-to-digital conversion and sampling the received signal portions of the echo signals and extraction of at least one sampling value for each signal portion; separately evaluating the sampling values for the different echo signals of the different emitted signals by means of a Fourier transformation stage and determining the frequency of the peaks corresponding to signal portions and determining a phase difference between the echo signals of the transmitted signals, characterised in that the signal portions of the second signal (B) are transmitted by means of the same frequencies as corresponding signal portions of the first signal (A).

    Abstract: The invention relates to a method for determining the distance and radial speed of an object relative to a measuring point, wherein the method comprises the following steps: a) emitting first transmission signals, which are radar radiation in the form of first frequency ramps, b) emitting second transmission signals, which are radar radiation in the form of second frequency ramps, wherein the second frequency ramps are different to the first frequency ramps, c) receiving received signals, which are first and second transmission signals reflected at the object, d) mixing the received signals with the first or second transmission signals to create mixed signals, e) creating a range-Doppler matrix using the mixed signals, f) detecting two Doppler frequencies, which originate from the radial speed of the object, and g) evaluating the Doppler frequencies and/or phase information of the mixed signals, such that ambiguities are eliminated when determining the radial speed wherein the first transmission signals and the second transmission signals are emitted at the same time.

    Abstract: The invention relates to a method for detecting road users along at least one traffic route, wherein the method comprises the following steps: emitting transmission signals by means of at least one transmission device for radar radiation, detecting received signals by means of at least one reception device for radar radiation, mixing the transmission signals and the received signals to produce baseband signals and calculating a detection matrix from the baseband signals and evaluating the detection matrix in an evaluation module of an electronic data processing device, wherein peaks of the detection matrix are assigned to objects, checking whether a disturbance criterion is met in a diagnostic module, generating signals from the results of the evaluation in the evaluation module and the check in the diagnostic module, and transmitting the signals to a control module of an electronic data processing device.

    Abstract: The intended position and/or an intended alignment of at least one sensor for monitoring traffic at a traffic route is determined easily, quickly and reliably with the aid of computer technology. The methodology employed involves identification of a traffic route to be monitored in a data processing device, and requesting and providing data about the traffic route from a database. From this, at least one possible target position and/or target orientation is determined from the provided data. The methodology avoids the need to manually enter lanes and other local conditions of the traffic route. Instead, the data processing device recalls the required traffic data from a database, and based on manipulation of a graphical representation of the sensor by the user with the aid of the provided data and specified sensor characteristics an intended position and/or intended alignment of a sensor can be visualized and stored for later use during installation.
