Webwave (L-FMCW) chirp sequence, whose frequency vs. time characteristic follows the sawtooth pattern shown in Figure 1 on the following page. The frequency f T (t) and phase F(t) of the linear FMCW transmit chirp are expressed as linear and quadratic functions of time, as shown in Figure 1. In a typical FMCW radar implementation (Figure 2 WebFMCW 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. Then the echo of the wave is captured at a receiver. A simplified block diagram of such a system is shown in Fig. 1 in which both the how are offices reopening
