High resolution radar for automobile applications

Abstract

Abstract. This contribution points out the potential of radar sensors with high resolution in azimuth and range in traffic environment and addresses some aspects of their practical implementation with respect to system design, hardware and software. A prototypical vehicle-based instrumentation radar is presented, which performs on-line acquisition and real-time visualisation of radar images with an update rate of up to 10 Hz. The enhanced perception capabilities of high resolution radar in traffic environment will be demonstrated with respect to new comfort and safety features, and practical realisation approaches concerning data processing and hardware including the scanning antenna will be discussed.

A Continuous Beam Steering Slotted Waveguide Antenna Using Rotating Dielectric Slabs

“…Special attention was paid to concept of a fixed antenna in which small parts are moved. Many such concepts have been presented in [3][4][5][6], as candidates for millimeter wave scanning antennas and in [7][8][9] for satellite communications. The Eagle Scanner of World War II was possibly the first electromechanically beam scanning antenna and included displacement of the narrow wall of a rectangular waveguide [10] in order to introduce phase shifting in a series-fed linear array.…”

The Perception System of Intelligent Ground Vehicles in All Weather Conditions: A Systematic Literature Review

“…The processing unit uses the captured signal to define target range, angle, and velocity. Based on applications, automotive radar sensors are categorized as short-range radar (SRR) (up to 30 m), medium-range radar (MRR), and long-range radar (LRR) (up to 250 m) [ 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 ]. Automotive radar systems typically run between 24 GHz and 76 GHz portions of the electromagnetic spectrum.…”

Optimized sensor placement for dependable roadside infrastructures

“…3) Scenario 3 -Parking garage: Third, we apply our optimization scheme to the scenario of an asymmetrically shaped parking garage containing various obstacles in the form of pillars and a separation wall. Monitoring in such a setup requires high accuracy and low sensitivity to illumination conditions, which is why we assume the deployment of high-precision radars with a narrow field of view [26] for high angular resolution. The solution spends 12 sensors to fully cover the garage, where favorable locations are for example found in the four corners (see Fig.…”
