Design Considerations for Integrated Radar Chirp Synthesizers

IEEE Access, 2019
Phase-locked loops (PLLs) effectively generate frequency chirps for frequency-modulated continuous-wave (FMCW) radar and are ideal for integrated circuit implementations.

Metasurface Antennas for FMCW Radar

IEEE Antennas and Wireless Propagation Letters, 2023
Two planar metasurface (MTS) antennas are designed to produce a pattern with optimal illumination in a radar scenario, given the a priori known path of the targets. The antennas are extremely flat, thin, with a monopole feed integrated in the plane of the structure. The monopole serves as a surface-wave (SW) launcher illuminating the slab.

Strategies for FMCW radars

2009 9th International Conference on Intelligent Transport Systems Telecommunications, (ITST), 2009
In this paper, we present a comparison of two strategies for FMCW radars. The potential presence of multiple targets implies using specific waveforms for beat frequencies association. Here, we compare performance of two such waveforms in terms of targets distance and velocity estimation.
