What is radar minima? I was studying the Aeronautical Chart User's Guide and I came across the term 'radar minima' several times under the graphics depicting charted airports.


  Blue – Airports with an Instrument Approach Procedure and/or
  RADAR MINIMA published in the high altitude DoD Flight
  Information Publications (FLIPs)
  
  Green – Airports which have an approved Instrument Approach
  Procedure and/or RADAR MINIMA published in either the
  U.S. Terminal Procedures Publications (TPPs) or the DoD FLIPs
  
  Brown – Airports without a published Instrument Approach
  Procedure or RADAR MINIMA
Published minimums for an ASR or PAR approach.

An ASR is essentially a non-precision approach with an MDA, while a PAR is a precision approach (found almost exclusively at military fields) with minimums of 200 and 1/2.
