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 distance and relative speed of an object remote from an observation point determined using a signal form which includes two signals having a predetermined spacing relative to each other. The two signals are transmitted for a certain time interval during which the frequency of the signals is modulated in a stepwise fashion. Additionally, the signal sections of the two signals are transmitted alternately for each step so that there is a predetermined frequency spacing between the signal sections being emitted consecutively.

摘要： In a method for operating a radar system, the object is to determine by simple means and at low cost the distance and/or the radial velocity of at least one target object with high resolution. For this purpose, in each measuring phase of the measurement process in the "pulse FMCW radar system", switchover between a transmission mode and a receiving mode is effected a multiple number of times and at short intervals of time. In the transmission mode, all receiving units of the radar system are switched off, while a pulse-shaped (frequency-modulated) transmission signal with time-successive transmission pulses having a specific pulse-on time and a specific carrier frequency is emitted from at least one transmitter unit of the radar system. In receiving mode, all transmitter units are switched off in the pulse-off times of the transmission pulses, while from at least one receiver unit all reflection signals originating from the last emitted transmission pulse are detected as received signal from the entire observation range before emission of the next transmission pulse. The distance and/or the radial velocity of the reflection objects is determined indirectly by the signal processing unit of the radar system by evaluation of the frequency difference and/or phase difference between the transmission signal and the received signal.
