Radar-on-Lidar: metric radar localization on prior lidar maps
Radar and lidar, provided by two different range sensors, each has pros and cons of various perception tasks on mobile robots or autonomous driving. In this paper, a Monte Carlo system is used to localize the robot with a rotating radar sensor on 2D ...

Metasurface Doppler Cloak for Broadband Radar Stealth
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 ...

Space scanning FMCW-based two-dimensional frequency diverse array radar
The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...
