FMCW RADAR SYSTEM FOR TRANSPONDER IDENTIFICATION

Progress In Electromagnetics Research B, 2018
—In this paper, we deal with a frequency modulated continuous wave (FMCW) radar used for localizing and tracking targets by frequency evaluation of the received radar beat signal. The radar system achieved with a primary radar (reader) and a secondary radar (transponder) is addressed as super high frequency (SHF) radio frequency identification (RFID ...

Processing and Resolution Losses Due to Range Cell Migration—Application to Automotive Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study analyzes how range cell migration (RCM) affects pulse compression and Doppler processing in high‐resolution radar systems. Theoretical models including RCM effects are developed for both pulse and frequency‐modulated continuous wave (FMCW) radar. Resolution and processing losses are quantified for FMCW, linearly frequency‐modulated (LFM) and
