Focusing Bistatic FMCW SAR Signal by Range Migration Algorithm Based on Fresnel Approximation
Sensors, 2015 Frequency modulated continuous wave (FMCW) technique has recently been employed by synthetic aperture radar (SAR) to decrease the radar cost and volume. However, the operation range is limited by the direct energy leakage from the transmitting channel to

DoA Estimation for FMCW Radar by 3D-CNN [PDF]
Sensors, 2021 A method of direction-of-arrival (DoA) estimation for FMCW (Frequency Modulated Continuous Wave) radar is presented. In addition to MUSIC, which is the popular high-resolution DoA estimation algorithm, deep learning has recently emerged as a very promising alternative.

High Resolution FMCW Level Gauge with Narrowband FMCW Radar [PDF]
The Journal of the Korean Institute of Information and Communication Engineering, 2012 Level Gauge using FMCW Radar is widely used and researched in many areas because of contactless, long range and flexibility. However FMCW level gauge requires wideband RF bandwidth for archiving high resolution of cm grade. In this paper we propose a new tx sawtooth waveform and processing algorithm with narrowband RF for wideband performance.
