  1. Overview of radars S. Cruz-Pol INEL 6069

  2. Types of Doppler Radar • Continuous Wave (CW) • Simple • No range information • Frequency Modulated CW, (FMCW) • Fine range resolution • Artifacts from target motion • Pulse Doppler • Range and Doppler • No artifacts (except when pulse compression used)

  3. FM Radar : Stationary target case Stationary Target fd=0 R = ctr/2

  4. FM Radar : Moving target case Moving Target fd not equal to 0

  5. How to find fd

  6. Pulse Doppler Radar

  7. Range Ambiguities
