    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: The present invention relates to a CW radar method for measuring distances between and relative speeds of a vehicle and one or more obstacles. The present invention further provides that the transmission (s(t)) can be composed of at least four consecutive chirps (A, B, C, D), each having different slopes. The intersection points of all lines in the distance-relative speed diagram from two chirps (A, B) can be calculated from all the ascertained frequency positions K1,n and K2,p. To validate those intersection points, one may observe whether a peak exists in the Fourier spectrum of a third chirp C at a frequency position K3,q, whose assigned line intersects a surrounding area of the intersection point in the distance-relative speed diagram. A further validation of those intersection points involves observing whether a peak exists in the Fourier spectrum of a fourth chirp D at a frequency position K4,r, whose assigned line intersects a surrounding area of the intersection point in the distance-relative speed diagram. The intersection points are then regarded as valid, when they satisfy both conditions.

    摘要: A measuring device , e.g., a measuring device for a motor vehicle, is for measuring a distance between the measuring device and at least one object and/or measuring a difference in speed between the measuring device and the at least one object. The measuring device includes an emitting apparatus for transmitting a transmission signal encompassing at least two sequences of signal portions, a first sequence of signal portions and a second sequence of signal portions with two respective temporally alternating signal portions. The frequency of at least two signal portions of a sequence of signal portions differs by one respective difference frequency, the difference frequency of the first sequence of signal portions being different from the difference frequency of the second sequence of signal portions.
