Prospects of FMCW-based frequency diverse array radar [PDF]

The Journal of Engineering, 2019
The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as

High-Resolution Localization Using Distributed MIMO FMCW Radars [PDF]

Sensors
Due to its fast processing time and robustness against harsh environmental conditions, the frequency modulated continuous waveform (FMCW) multiple-input multiple-output (MIMO) radar is widely used for target localization.

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 ...

FMCW-Radar-Based Electronic Walking Cane for Blind Pedestrians [PDF]

, 2020
Our new idea of using a simple FMCW radar as an electronic walking cane is described. The letter goes beyond the idea by proposing the required architecture architecture, and even proposed antenna type and usable COTS part numbers.

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 ...
