In this paper a processing algorithm that allows for estimating the velocity of multiple reflecting objects with standard OFDM communication signals is discussed. This algorithm does not require any specific coding of the transmit data. The technique can be used in combination with a range estimation algorithm in order to implement active radar sensing functions into a communication system for vehicular...
On the basis of a previous one-axis accelerometer motion compensation system for automotive SAR, an updated scheme is presented in this paper, which contains a one-axis gyroscope and two-axis accelerometer. The requirement for extra Degrees of Freedom (DoF) leads to a new motion signal model. The complete procedure of calculating motion deviation in image display plane (IDP) from the raw roll angle...
Automotive radar is a fast growing application and improves safety and comfort for all road users. As in other hightech related fields of work, the development process of such devices and functions benefits tremendously from the modern measurement equipment as well as from adequate simulations. To use simulations as far as possible becomes attractive since measurements are time consuming. To enhance...
In this paper an approach will be presented that allows for estimating the velocity of multiple reflecting objects with standard OFDM communication signals. The proposed technique does not require any specific coding of the transmit signal and provides high dynamic range and low sidelobe levels. This allows for an efficient acquisition of velocity information in joint communication and radar systems...
In this paper a simulation approach is presented, that allows for virtually investigating the performance of automotive radar systems regarding different system parameters. This is achieved by combining dedicated simulation models for the radar transmitter and receiver with a deterministic propagation simulator based on ray tracing. This approach is in particular suitable for investigating the capabilities...
In this paper the applicability of beam-forming algorithms in radar systems operating with OFDM signals is investigated. It is shown that beam-forming techniques can be directly applied to the output of an OFDM radar processor in order to calculate two-dimensional radar images in distance and azimuth. With a dedicated system model including a realistic road scenario propagation simulator, the performance...
An antenna concept for compact millimeter-wave radar sensors that desire a fan-beam radiation pattern is proposed. It combines an end-fire antenna on a ceramic substrate with a cylindrical parabolic reflector that can be integrated in the sensor's metal housing. The concept allows a direct interconnection from the active components to the antenna in a flip-chip attachment. It is validated with a 77-GHz...
