An Approach to Over-the-air Synchronization of Commercial Chirp-Sequence Automotive Radar Sensors

An approach to wireless synchronization be- tween two commercial 77GHz automotive FMCW radar sensors is shown. In particular, our main concern is the align- ment of a passive listening sensor to a second active trans- mitting sensor in frequency, …

In-Situ Time-Frequency Analysis of the 77 GHz Bands using a Commercial Chirp-Sequence Automotive FMCW Radar Sensor

A commercial chirp-sequence automotive radar sensor is reconfigured to allow for time-frequency analysis of the 77 GHz automotive radar bands. Compared to highend measurement equipment such as real-time spectrum analyzers, due to its low cost and …

Single-Snapshot Direction-of-Arrival Estimation of Multiple Targets using a Multi-Layer Perceptron

An alternative approach to high-resolution direction-of-arrival estimation in the context of automotive FMCW signal processing is shown by training a neural network with simulation as well as experimental data to estimate the mean and distance of the …

Model Order Estimation using a Multi-Layer Perceptron for Direction-of-Arrival Estimation in Automotive Radar Sensors

In this work, a machine-learning-based approach to decide whether one or two targets are present in the same range-velocity cell of a chirp-sequence FMCW radar system is evaluated. An experimental setup for generating sufficient large sets of …

A Multi-Layer Perceptron Applied To Number Of Target Indication For Direction-Of-Arrival Estimation In Automotive Radar Sensors

A multi-layer perceptron for indicating the number of targets present in a range-velocity cell of automotive radar sensors is examined and compared with a state-of-the-art approach based on a Generalized Likelihood Ratio Test. The multi-target …

Smart Communication and Relative Localization System for Firefighters and Rescuers

This paper presents a smart communication system for simultaneous data reception and direction of arrival estimation for firefighters, rescuers, and other emergency personnel. The system consists of a passive six-port microwave interferometer which …

Low Latency Evaluation of an Adaptive Industrial Wireless Communications System for ISM Bands

Low latency and highest transmission reliability are the key challenges for enabling time-critical industrial wireless applications, e.g. in factory automation. Both are significantly determined by the rough and dynamic environmental conditions as …
