WebThe use and processing of the FMCW signal for radar and acoustic sounder systems are examined. This signal--along with real-time digital processing via minicomputers--is currently being used by several groups for HF over-the-horizon radars. WebAn FM-CW radar is a few steps more advanced than the very basic Doppler radars (like the HB-100), typically: I and Q outputs as described above Modulation input, that allows you to quickly sweep the radar frequency The basic idea behind an FM-CW radar is that the frequency is sweeped, at some continuous rate.
