IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020 Frequency-modulated continuous-wave (FMCW) synthetic aperture radar (SAR) systems represent an effective solution for observing the earth surface. Although they have recently grown in popularity, FMCW SAR raw signals are sometimes not open access, thus preventing the user from performing those processing techniques designed in the raw domain.

FMCW radar with broadband communication capability [PDF]
2007 European Radar Conference, 2007 The use of amplitude modulation to encode information onto an FMCW radar signal is proposed in this paper. This new technique, that has been named AM-FMCW communicating radar, provides a new channel for broadband communication by reusing the radar frequencies and without introducing any distortion in the radar functionality.

Orthogonal waveforms for FMCW MIMO radar [PDF]
2011 IEEE RadarCon (RADAR), 2011 Multiple input/multiple output (MIMO) radar system performance benefits from the capability to simultaneously transmit and receive multiple orthogonal waveforms. For pulse radars fitting orthogonal waveforms have been developed. These waveforms are however not necessarily suitable for frequency-modulated continuous-wave (FMCW) radar.

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

Experimental Comparison of IR-UWB Radar and FMCW Radar for Vital Signs
Sensors, 2020 In this paper, we compare the performances of impulse radio ultra-wideband (IR-UWB) and frequency modulation continuous wave (FMCW) radars in measuring noncontact vital signs such as respiration rate and heart rate. These two type radars have been widely

Implementation of FMCW radar for training applications [PDF]
2017 4th International Conference on Electrical and Electronic Engineering (ICEEE), 2017 In this study, a frequency modulated continuous wave (FMCW) radar has been implemented. The FMCW is obtained by modulating CW signal. The triangular wave signal has been selected as modulation signal and a modulator circuit has been performed. The FMCW radar system provides the target velocity and range information in sufficient resolution within a 100-
