AbstractIn this paper, an orthogonal frequency-division multiplexing (OFDM) waveform radar sensing approach is demonstrated based on field measurements at C-band. We demonstrate a concept that is based on the exploitation of typical wireless communication transmissions to perform passive, distributed radar sensing. Our concept is based on an OFDM radar that operates in the modulation symbol domain and can be well integrated into existing OFDM receivers. The measurement setup and the signal processing steps for the OFDM radar are described. The results show that the passive, distributed radar sensing approach can be used to detect and localize moving cars and even pedestrians in automotive intersection scenarios.

Abstract Emerging wireless communication and radar sensing systems require large channel bandwidths to meet the requirements of some key applications. Antennas used for the development of these systems must be designed to enable these large bandwidths. In this work, we present the characteristics of a quasi-half loop bond wire antenna (QHL-BWA) which enable large bandwidths and high gains at mmWave frequencies. The antenna was modelled and simulated using Ansys HFSS. Test samples were designed and measured. Very good correlation was obtained between measurement and simulation results.
