Abstract: 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.

Abstract: A vehicle radar emits four groups of single-frequency stepped radar pulses. In group A, the frequency of each pulse is a fixed amount higher than that of the preceding pulse. In group B, the frequency of each pulse is a fixed amount lower than that of the preceding pulse. In group C, the frequency of each pulse is the same as that of the preceding pulse. In group D, the frequency of each pulse depends on a modulo algorithm. The signals reflected from other vehicles may readily be processed with inexpensive equipment to discriminate among such other vehicles, and to determine the distance to, and relative speed of, each such vehicle.

Abstract: Contactless measurement of the distance traveled by a vehicle during selected time intervals is provided by a device operating on the Doppler principle. The device has a "phase-locked loop" circuit which generates pulse signals having a frequency proportional to the vehicle velocity. Using the pulses as path length increases, the pulses are added in a counter and the counter output is supplied to an indicating unit to indicate the distance traveled by the vehicle.

Abstract: A radar sensor and a radar antenna are for monitoring the environment of a motor vehicle. A compact construction is achieved by the planar array of both the control circuit and the radar antenna, so that the radar sensor may be located, for example, in the area of a motor-vehicle bumper. Example configurations consist of the separate line support for arranging lines to transmit high-frequency signals between the control circuit and the radar antenna and the configuration of the radar antenna as a Rotman lens, in relation to the signal propagation times and the layered arrangement of Rotman lens and group antenna.

Abstract: In the particular embodiment disclosed in the specification, a CW radar process for measurement of distances and relative speeds between a vehicle and one or more obstructions including transmitting a sequence of constant-frequency radar signal bursts which follow one another without any time interval during four successive measurements. In the first measurement, the radar signal bursts are of sequentially increasing frequency and in the second measurement they are of sequentially decreasing frequency while in the third measurement they have the same frequency and in the fourth measurement the burst frequencies follow a coded pattern. Demodulation of the signals which are reflected by obstructions is carried out by mixing them with the transmitted signals using only one single-channel mixer providing an output signal which is not the signal of a phase curve but of an amplitude curve.
