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

FMCW Radar Performance for Atmospheric Measurements [PDF]
Radioengineering, 2010 Frequency-modulated continuous-wave radars (FMCW) have been used in the investigation of the atmosphere since the late 1960’s. FMCW radars provide tremendous sensitivity and spatial resolution compared to their pulsed counterparts and are therefore ...

SAR ADC for a Multimode Radar Transceiver with Offset Calibration [PDF]
Journal of Electromagnetic Engineering and Science, 2022 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 ...

A Study on the Feasibility of Stop-and-Go Approximation in FMCW SAR [PDF]
Journal of Electromagnetic Engineering and Science, 2022 Synthetic aperture radar (SAR) specializes in capturing two-dimensional images of Earth’s surface. Because satellites or aircraft have mainly been used as SAR platforms, pulse radar systems with high peak transmitted power have been preferred for long ...

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.
