Eleven incoherent scatter radars, including the recent addition of the Poker Flat Radar in Alaska, are now in operation around the World. Professor Hagfors made important contributions to many of these facilities, and indeed directed or worked at more than half of them. No two radars are alike, all develop and change with time, and their capabilities, goals and programs vary. This presentation will document, compare and review the existing radars providing an up to date summary of the capabilities of these powerful instruments.
