               NORAD-USNORTHCOM/J84
                                                          UNCLASSIFIED

                                                   Requirements

  1)   Faster detect, track establishment, and initial assessment
  2)   Faster track correlations with cooperative data
  3)   Report one track per target
  4)   Flag targets that go from cooperative to non-cooperative
  5)   Better coverage of lower altitudes
  6)   Better 3-dimensional positional accuracy
  7)   Detect and track targets with smaller radar cross sections
  8)   Bird Strike Mitigation / Flock Detection
