摘要： In a method for determination of the length of objects in traffic, especially passenger cars, trucks, buses, motorbikes, bicycles and pedestrians, radar signals are transmitted by a vehicle, the radar signals are reflected by an object being measured, the reflected radar signals are received in the vehicle, the frequency spectra of the reflected radar signals are evaluated, and the reflection peaks contained in the frequency spectra are determined. Length measurement, by means of known radar sensors, from a vehicle is made possible by the fact that the width of the reflection peaks is determined, and that the length of the object being measured is determined by means of the determined width.

摘要： The invention relates to a distance measuring device. A transmitting part (E) for electromagnetic radiation especially radar radiation, emits measuring pulses (A, B) which are controlled by a pulse generator (1), and a receiving part (8) is switched to a ready-to-receive mode after a certain, adjustable delay (TDELAY, before a next measuring pulse is emitted, for receiving a reflected pulse during a time gate (18). The aim of the invention is to provide a calibration process taking into account all practical defects. To this end, the pulse generator (1) produces pulses with a multiple of the frequency with which the measuring pulses are repeated and a calibrating cycle in which calibrating pulses (&tgr;0 to &tgr;9) are produced with pulses generated by the pulse generator (1), controlled by the transmitting part (5), is carried out at longer intervals in time. The calibrating pulses (&tgr;0 to &tgr;9) are received directly in the receiving part (8) and the delay time (TDELAY) In the receiving part is regulated in such a way that a generated calibrating pulse (&tgr;0) to &tgr;9) is received directly by the received directly by the receiving part (8) during a time gate (18).

摘要： The invention relates to a sensor comprising a housing, inside of which a transmitting antenna array that transmits electromagnetic transmission signals in a radiation area and a receiving antenna array that receives received signals reflected by at least one object located within the radiation area are provided. The inventive sensor is designed in such a manner that the transmitting antenna array is provided for transmitting transmission signals in a main radiation area (3) and in a secondary radiation area (4) situated at an angle, thereto, and in that the receiving antenna array (TX) is provided for receiving received signals reflected in both radiation areas (3, 4). This makes it possible, for example when used in a monitor vehicle (5), to monitor the area behind and next to the motor vehicle (5) with a single transmitting antenna (1).

摘要： A radar system is operated by controlling and thereby limiting the mean power of the transmitted signal in response to the mean power of the received signal thereby limiting the power to a predetermined power range. Preferably the power control or regulation is performed by varying the pulse repetition frequency and/or the pulse duration of the transmitter pulses. This method is well suited for operating a motor vehicle range warning system.
