WebFMCW radar is used and the corrective result is good. 2. Algorithm Description In general, the compensation method mentioned in this paper can only be used to images which contain a dominate scatters. However the range profile is blurred because of the nonlinearity of the LFM(Linear Frequency Modulation) signal[5]. WebJun 10, 2024 · 1 Answer. The principle behind FMCW is that you transmit a chirped signal and receive a time delayed version of it after reflecting from a target. After mixing and filtering, the resulting signal is a sinusoid at a frequency that is a function of the target's range. This frequency is known as the "beat" frequency f b.
FMCW radar (Frequency-Modulated Continuous Wave radar = FMCW radar) is a special type of radar sensor which radiates continuous transmission power like a simple continuous wave radar (CW-Radar).
