Enabling Joint Radar-Communication Operation in Shift Register-Based PMCW Radars
Lucas Giroto de Oliveira, Elizabeth Bekker, Axel Diewald +5
This article introduces adaptations to the conventional frame structure in binary phase-modulated continuous wave (PMCW) radars with sequence generation via linear-feedbck shift re…
Bistatic OFDM-based Joint Radar-Communication: Synchronization, Data Communication and Sensing
Lucas Giroto de Oliveira, David Brunner, Axel Diewald +4
This article introduces a bistatic joint radar-communication (RadCom) system based on orthogonal frequency-division multiplexing (OFDM). In this context, the adopted OFDM frame str…
Slice-Less Optical Arbitrary Waveform Measurement (OAWM) in a Bandwidth of More than 600 GHz Using Soliton Microcombs
Daniel Drayss, Dengyang Fang, Christoph Füllner +10
We propose and demonstrate a novel scheme for optical arbitrary waveform measurement (OAWM) that exploits chip-scale Kerr soliton combs as highly scalable multiwavelength local osc…
Discrete-Fresnel Domain Channel Estimation in OCDM-based Radar Systems
Lucas Giroto de Oliveira, Benjamin Nuss, Mohamad Basim Alabd +7
In recent years, orthogonal chirp-division multiplexing (OCDM) has been increasingly considered as an alternative multicarrier scheme, e.g., to orthogonal frequency-division multip…
Quasi-Monostatic Antenna Displacement in Radar Target Simulation
Axel Diewald, Benjamin Nuss, Thomas Zwick
Radar target simulators (RTS) have recently drawn much attention in research and commercial development, as they are capable of performing over-the-air validation tests under labor…
Two-Dimensional Arbitrary Angle of Arrival in Radar Target Simulation
Axel Diewald, Benjamin Nuss, Johannes Galinsky +1
Automotive radar sensors play a key role in the current development of advanced driver assistance systems (ADAS). Their ability to detect objects even under adverse weather conditi…
Hybrid Electro-Optic Modulator Combining Silicon Photonic Slot Waveguides with High-k Radio-Frequency Slotlines
Sandeep Ummethala, Juned N. Kemal, Ahmed S. Alam +10
Electro-optic (EO) modulators rely on interaction of optical and electrical signals with second-order nonlinear media. For the optical signal, this interaction can be strongly enha…
Wireless THz link with optoelectronic transmitter and receiver
Tobias Harter, Sandeep Ummethala, Matthias Blaicher +15
Photonics might play a key role in future wireless communication systems that operate at THz carrier frequencies. A prime example is the generation of THz data streams by mixing op…
THz-to-Optical Conversion in Wireless Communications Using an Ultra-Broadband Plasmonic Modulator
Sandeep Ummethala, Tobias Harter, Kira Koehnle +14
Future wireless communication networks have to handle data rates of tens or even hundreds of Gbit/s per link, requiring carrier frequencies in the unallocated terahertz (THz) spect…
Frequency-Multiplexed bias and readout of a 16-pixel Superconducting Nanowire Single-Photon Detector Array
Steffen Doerner, Artem Kuzmin, Stefan Wuensch +4
We demonstrate a 16-pixel array of radio-frequency superconducting nanowire single-photon detectors with an integrated and scalable frequency-division multiplexing architecture, re…
