Automotive radar target tracking by Kalman filtering
Automotive radars have been introduced successfully into the consumer market with sensors in the 24- and 77-GHz domain [1]. In order to increase traffic safety, an application for detecting and tracking Vulnerable Road Users (VRU) and vehicles in front of the car is currently under development. By using a single 24-GHz radar sensor, target parameters like range, radial velocity and azimuth angle are measured even in multiple target scenarios. This paper describes the current implementation progress of a signal processing scheme for target tracking by Kalman filtering and presents tracking results using real measurement data. The work is developed under the FP7 EC funded project ARTRAC [2].
Integrated 79GHz UWB automotive radar front-end based on Hi-Mission MCM-D silicon platform
A highly integrated silicon platform (Hi-Mission) for high frequency applications is introduced. This platform utilizes heterogeneous MCM-D technology with integrated passive devices together with silicon and GaAs MMIC technology developed for the automotive UWB radar (SRR) frequency band from 77 – 81 GHz. Developments are described in the area of MCM-D process development, MMIC, integrated phased array antenna, module design and assembly process development. The demonstrator is composed of two test vehicles designed for conducted and radiated measurements respectively. Test results are presented at the component and module level.
A 24 GHz short range radar network for automotive applications
For automotive short range applications, i.e. for distances up to 20 m, at the Technical University of Hamburg a radar network based on cheap 24 GHz high range resolution pulse radar technology was integrated into an experimental vehicle and tested in a real street environment. This paper presents a description of the network design, the individual pulse radar sensors, the network signal processing and possible automotive applications of the radar network, respectively. Object position estimation is accomplished by the very precise range measurement of each individual sensor and additional multilateration procedures. This radar network has been integrated into the front bumper of an experimental car for detailed measurement campaign in normal street and traffic situations. The paper concludes with a few results measured with the experimental vehicle in realistic traffic conditions.
