Multi-Band FMCW Signal Generator with a Tunable Sweep-Frequency Bandwidth and Inter-Band Interval

Photonics
In this work, we experimentally demonstrate a scheme for generating a multi-band FMCW signal with a tunable sweep bandwidth and inter-band interval. For such a scheme, an original FMCW signal is first acquired by directly current-modulating a master ...

A FMCW-FSK Combined Waveform for Multi-Target Detection in FMCW Radar

DEStech Transactions on Computer Science and Engineering, 2017
Frequency modulated continuous wave (FMCW) radar has been widely applied in many fields. Modulated waveform is usually designed to solve the coupling problem of range and velocity in multi-target situation. A FMCW-FSK combined waveform is proposed in this work, which takes the advantages of FMCW waveform and FSK waveform.

Digital FMCW for ultrawideband spectrum sensing [PDF]

Radio Science, 2016
AbstractAn ultrawideband digital frequency‐modulated continuous wave sensing engine is proposed as an alternative technique for cognitive radio applications. A dual‐band demonstrator capable of sensing 750 MHz bandwidth in 204.8 µs is presented. Its performance is illustrated from both bench tests and from real‐time measurements of the GSM 900 band and

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...
