Webare licensed ISM frequencies, approved for “through air microwave transmission. Output power of most systems is very low, enough to be used with persons in the area, although some manufacturers do have restrictions to closed vessels only. Low frequency devices were the most prevalent, as was FMCW systems, which used Webthe desired maximum distance, which is chosen as 1 m in air, Tsweep is determined as 8 ms. With this choice, a maximum distance of 6 m can be achieved in water. If cUS is the speed of sound in air and BW is the bandwidth of the chirp signals, the smallest distance step that can be measured using FMCW is (cUS/2BW). To keep it about
WebLet’s review the operating principle behind FMCW radars. In FMCW radar solutions, the transmitted signal is a linear frequency-modulated continuous wave (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
