Es ist die Aufgabe der hier vorliegenden Erfindung, die Länge von Umgebungsobjekten mit einem Radarsystem zu erfassen.It is the object of the present invention, the length of To capture environmental objects with a radar system.
Diese Aufgabe ist erfindungsgemäß gelöst durch ein Sensorsystem und ein Verfahren gemäß den unabhängigen Patentansprüchen. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.These The object is achieved by a sensor system and a method according to the independent claims. Advantageous developments are the dependent claims refer to.
Es wird ein Radarsystem zur Umfelderfassung eines Kraftfahrzeugs mit Sendemitteln zur gerichteten Abstrahlung von Sendeleistung, Empfangsmitteln zum gerichteten Empfang von an Objekten reflektierter Sendeleistung und Signalverarbeitungsmitteln zur Prozessierung der empfangenen Leistung angegeben. Die Frequenz der abgestrahlten Sendeleistung ist derart moduliert, dass sie im Wesentlichen aus einer Folge linearer Rampen gleicher Steigung besteht. In den Signalverarbeitungsmitteln wird einem Signal mit der momentanen Sendefrequenz und das von den Empfangsmitteln empfangene Signal gemischt. Das Ausgangssignal der Mischung wird gegebenenfalls nach geeigneter Vorverarbeitung während zumindest zweier Frequenzrampen abgetastet. Über die Abtastwerte jeder Rampe wird gegebenenfalls nach geeigneter Vorverarbeitung eine erste Spektralanalyse in Form einer diskreten Fouriertransformation gerechnet. Die Werte sind in Abhängigkeit von Ihrer Frequenz Rasterpunkten zugeordnet, welche bei entsprechender Auslegung in erster Näherung zur Objektentfernung korrespondieren. Zumindest für einen Teil der Rasterpunkte wird gegebenenfalls nach geeigneter Vorverarbeitung eine zweite Spektralanalyse über am jeweiligen Rasterpunkt in mehreren Frequenzrampen anfallende Werte durchgeführt, um spektrale Leitungsspitzen am jeweiligen Rasterpunkt zu detektieren; die Frequenz dieser Leistungsspitzen korrespondiert bei entsprechender Auslegung in erster Näherung zur Relativgeschwindigkeit von Objekten. Aus dem sich über aufeinander folgende oder wenig beabstandete Rasterpunkte ergebenden Amplitudenverlauf von Leistungsspitzen näherungsweise gleicher Frequenz wird auf die radiale Ausdehnung von Objekten geschlossen.It is a radar system for environment detection of a motor vehicle with Transmission means for directional emission of transmission power, receiving means for directionally receiving transmission power reflected at objects and signal processing means for processing the received ones Power indicated. The frequency of the radiated transmission power is modulated to be essentially a series of linear Ramps of the same slope exists. In the signal processing means is a signal with the current transmission frequency and that of the Reception received signal mixed. The output signal of Mixture is optionally after suitable preprocessing during at least sampled two frequency ramps. About the samples of each ramp If appropriate, after suitable preprocessing, a first spectral analysis calculated in the form of a discrete Fourier transformation. The values are dependent assigned by your frequency grid points, which at appropriate Interpretation in first approximation correspond to the object distance. At least for one Part of the screen dots is optionally after suitable preprocessing a second spectral analysis over at the respective grid point in several frequency ramps resulting values carried out, to detect spectral line peaks at the respective grid point; the frequency of these power peaks corresponds with appropriate Interpretation in first approximation relative velocity of objects. Out of each other over each other following or little spaced grid points resulting amplitude curve of power peaks approximately same frequency is closed to the radial extent of objects.
In einer vorteilhaften Ausgestaltung der Erfindung wird zur Bestimmung der radialen Objektausdehnung die Steigung der linearen Frequenzrampen, die ein Maß für die räumliche Ausdehnung des Bereichs darstellt, der in einem Rasterpunkt abgebildet wird, und die Zahl von aufeinander folgenden Rasterpunkten mit Leistungsspitzen näherungsweise gleicher Frequenz und über einer vorgegebenen Schwelle liegenden Amplitude benutzt wird. In einer besonderen Ausgestaltung der Erfindung wird die Schwelle für die Amplituden der Leistungsspitzen auf das Rauschniveau bezogen.

Für mehrere
Ziele i in der Umgebung kommt es zu einer lineare Überlagerung
von Frequenzen fi = 2ri/c·FR/TR.
In dem hier vorgestellten Radarsystem werden Sende- und Empfangssignal
einem Mischer zugeführt.
Am Mischerausgang wird nach Verstärkung und Filterung das Signal
abgetastet. Als Abtastzeitraum wird z. B. TRA = 12.8 μs gewählt. Die
ersten 3.2 μs
nach Beginn der Rampe des Sendestrahls werden nicht abgetastet,
da Filtereinschwingzeiten zu beachten sind und da das Empfangssignal
um die Laufzeit verzögert
am Empfänger
ankommt, z. B. beträgt
die Laufzeit 1.2 μs
bei einem Ziel in 180 m Entfernung, und die Messelektronik Zeit
für Einschwingvorgänge benötigt. Die
Zahl der abgetasteten Werte beträgt
in diesem Ausführungsbeispiel
M = 512, die Abtastfrequenz fA = M/TRA = 40 MHz. In
