An Adversarial Super-Resolution Remedy for Radar Design Trade-offs

, 2019
Radar is of vital importance in many fields, such as autonomous driving, safety and surveillance applications. However, it suffers from stringent constraints on its design parametrization leading to multiple trade-offs. For example, the bandwidth in FMCW

Metasurface Doppler Cloak for Broadband Radar Stealth

Advanced Physics Research, Volume 4, Issue 10, October 2025.
Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...

Phase Noise in FMCW Radar Systems [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2019
Phase noise is one of the fundamental performance parameters in modern radar, communication, spectroscopic, and metrological systems. In this paper, a phase noise theory has been developed for FMCW radar systems. A new design equation has been derived to specify the maximum bound on the allowable source phase noise level in radar systems. The nonlinear
