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.

Focusing Bistatic FMCW SAR Signal by Range Migration Algorithm Based on Fresnel Approximation
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
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

Compressed Sensing for THz FMCW Radar 3D Imaging
A terahertz (THz) frequency-modulated continuous wave (FMCW) imaging radar system is developed for high-resolution 3D imaging recently. Aiming at the problems of long data acquisition periods and large sample sizes for the developed imaging system, an ...

FMCW radar with broadband communication capability [PDF]
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
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.

SAR ADC for a Multimode Radar Transceiver with Offset Calibration [PDF]
In this paper, we design a successive approximation register (SAR) analog-to-digital converter (ADC) suitable for multimode radar transceivers. For multimode radars, the sampling rate required by ADC varies according to the continuous wave (CW) or ...
