As a geeky post-war child, I grew up reading R V Jones' populist histories of wartime technology, particularly radar. Dogma was that radar was a British invention, jealously guarded lest any enemy discover its secret. This book sets a few of those myths straight; that the cavity magnetron was invented independently by almost everyone (and even published pre-war) and the sophistication and historical significance of Japanese microwave naval radar, are just a couple. Experts in the field probably knew many of these issues already, but for "armchair experts" like myself, looking for a technically detailed coverage that goes beyond RV Jones, and looks beyond the air war over Europe, then this is a book to have.
This is a brilliant book which contains much hard to find information. It is very comprehensive and is almost the last word on the subject. Why almost? It seems there are some gaps on Russian WW2 radar development. Bill Gunston in his foreword to `Soviet Combat Aircraft of the Second World War Volume 2'refers to the Gneis interception radar, introduced during the Stalingrad period.Brown does not mention this but a book of this nature takes years to research and obviously the latest information on Russian radar development became available too late. Nevertheless for serious students of WW2 this is a `must-have' book.
