FMCW radar is a special type of radar sensor that radiates continuous transmission energy as a simple continuous-wave radar (CW-Radar). In contrast to this CW radar the FMCW radar can change its operating frequency during the measurement: ie, the transmission signal is frequency (or phase) modulated. The possibilities of radar measurements. . . Also, in FMCW radars the vital sign information is encoded in the received phase similar to FM signals. Thus, FMCW radar is less affected by the noise in comparison to impulse radars. 2.1FMCW radar basics In any radar, the electromagnetic wave is sent into the environment containing various objects.

In this report, the radar is implemented by means ofthe software GNU Radio Companion with a test signal. It has been a while since I used the FMCW block in the Radar toolbox, but from what I can remember, the three samples sections are defining the percentage of the signal you want distributed in each of those sections. For example, if you want 50% of your signal to be CW, and 50% to be up-chirp, put an equal number of samples in the Samples CW. A linear / stepped frequency modulated continuous wave (FMCW) signal has for a long time been used in radar and channel sounding. A novel FMCW waveform known as "Gated FMCW" signal is proposed in this thesis for the s uppression of strong undesired signals in microwave radar applications, such as: through-the-wall,. objects, but can be generated using of frequency modulation of the transmitted signal. In this method, a signal is transmitted, which changes periodically in the frequency. When an echo signal is received, that change of frequency gets a delay Δt (by runtime shift) like to as the pulse radar technique. Table of Content « FMCW-Radar » 1.
