摘要： The invention relates to a method for simulating echo signals for Doppler radar systems, whereby a radar signal transmitted by a Doppler radar system is received by a simulator, is subjected to the action of a Doppler frequency shift, and is transmitted back to the Doppler radar system as a simulated echo signal. According to the invention, an additional Doppler radar system or Doppler radar front end which is equipped with at least one switch is used as a simulator, and the switch is switched over with a frequency (fD) which corresponds to the Doppler frequency shift to be simulated.

摘要： A synthesizer combines frequencies for multiple targets, accumulating the phase components separately and allowing the targets to change velocity separately. The amplitude of the simulated signal at the phase specified is generated using a method that combines coarse and fine angle components of the desired angle signal allowing small high speed memories to be used. A first ROM is addressed by high order bits of the phase component and a second ROM by the lower order bits. The outputs of the first and second ROM's are multiplied and then added to the output of the first ROM producing the amplitude of the desired phase. The system also allows the amplitude of the signal being synthesized to be modulated by multiplying the synthesized digital value by an amplitude modulator. The synthesized amplitudes for each frequency are combined. Digital zero order hold correction removes amplitude distortion from the output spectrum. Separate target profiles for multiple targets can be simulated in high detail as the radar simulates a target illumination sweep by a profile memory addressed by the filtered combination. By providing the angle components to in-phase and quadrature generators the system will simulate digital signals for digital radars. After the filtered value is converted into an analog echo signal, a programmable lowpass filter, with a passband adjustable based on the number of targets being simulated, adjusts the passband to suppress undesired components.

摘要： A method and apparatus for determining misalignment of a radar sensor unit mounted to a vehicle includes providing targets on an alignment apparatus. A vehicle is located at predetermined location on a test station an exact given distance from the alignment apparatus. The actual locations and distances of the targets from each other and from radar sensor unit of the vehicle at the test station are known and pre-stored. At least one target is a greater distance from the vehicle than the other targets. The targets receive and return a radar wave from the radar sensor unit. The radar sensor unit determines locations and distances of the targets and compares with the given or actual locations and distances of the targets to determine misalignment of the radar sensor unit. A calibration program automatically calibrates azimuth and elevation to adjust for misalignment.

摘要： A vehicle detection system for determining the position of a trailing section relative to a forward section of a vehicle, such as a tractor-trailer combination. The trailing section is pivotally coupled to the forward section for driving movement therewith. The vehicle detection system includes a central controller and a detection system connectable to the forward section of the vehicle and operably coupled to the central controller. The detection system outputs a detection signal. A target device is connectable to the trailing section and configured to receive the detection signal from the detection system and output a unique return signal to the detection system. The detection system receives the return signal and transfers the return signal or other indicative signal for processing by the central controller, whereby the central controller determines position information of the trailing section, for potential use by a DSRC.

摘要： A method and system are described for measuring displacements and vibrations of an object /structure (P). The method comprises the following steps: transmission of at least one radar wave by a single radar device (Q) positioned at a predefined distance (R) from a receiver device (10) applied on the object /structure (P); reception, by the radar device (Q), of a complex signal (s(t)) consisting of the sum of the signal reflected from said receiver device (10) and of one or more interfering signals (I) generated by one or more corresponding targets (I 1 , I 2 ) substantially stationary and substantially positioned at the same distance (R) from the radar device (Q); separation of the interfering signals (I) from the reflected signal. The separation step comprises a calibration step which consists in the induction, for a pre-determined period of time, of a vibrational motion having a known frequency and duration in the receiver device (10), which consequently operates as a calibration device, for obtaining an estimated value of the interfering signals (I), and in the subtraction of the estimated value of the interfering signals (I) from the complex signal (s(t)), in order to substantially eliminate said one or more interfering signals (I) and obtain the entity of the displacement of the object /structure (P) on the basis of the reflected signal.
