Radar Frequencies and Waveforms - ITS
www.its.bldrdoc.govA radar system probes its environment with specially designed waveforms to identify and characterize targets of interest. Detection For a given range, angle, and/or Doppler, decide if a target is or is not present. Example: Moving target indication (MTI) radar Estimation For a given range, angle, and/or Doppler, estimate
