Abstract
FMCW Radar (Frequency Modulated Continuous Wave Radar) is used for various purposes, such as atmospheric Remote Sensing, inter-vehicle ranging, etc. FMCW radar systems are usually very compact, relatively cheap in purchase as well as in daily use, and consume little power. In this paper, FMCW radar determines a target range by measuring the beat frequency between a transmitted signal and the received signal from the target, and Combines between PO and radar single. The approach based on frequency domain physical optics for the scattering estimation and the linear system modeling for the estimation of time domain response, and FMCW Radar signal processing.
Highlights
The FMCW radar has to adjust the range of frequencies of operation to suit the material and targets under investigation

The value of the received-signal frequency compared to the transmitted-signal frequency is proportional to the propagation range
Summary
The FMCW radar has to adjust the range of frequencies of operation to suit the material and targets under investigation. The further advantage of FMCW radar is its ability to adjust the range of frequencies of operation to suit the material and targets under investigation if the antenna has an adequate pass-band of frequencies. This radar system mixes the wave reflected by a target object and part of the radiated wave to obtain a beat signal that contains distance and speed components. By mixing the received FMCW and transmitted FMCW signals, the system obtains a beat signal having a frequency f b
