Web10 jul. 2024 · Figure 13: Frequency resolution equals bandwidth (Fmax) divided by spectral lines (SL) The eight frequency domain spectral lines are spread evenly between 0 and 16 Hertz, which results in the 2.0 Hertz spacing on the frequency axis. Note that 0 Hertz is not included in the spectral line total. WebA form of pulse radar that uses the Doppler frequency shift to eliminate stationary clutter is called either a moving-target indication (MTI) radar or a pulse Doppler radar, depending on the particular parameters of the signal waveform. The above measurements of range, angle, and radial velocity assume that the target is a “point-scatterer.”.
