German Radar in the Netherlands 1940-1945

This publication focuses on (semi-) permanent radar equipment of the German Air Force and Navy deployed in the Netherlands during the Second World War, as well as on the structures intended for this purpose.   The book describes the development of radar in various countries in the run-up to World War II. The conquest of our country gave the occupiers the optimal opportunity to deploy radar devices of the air force and navy. One of the most authoritative authors in the field of German radar, Dr. F. Trenkle, describes more than 300 radar types and variants. It is certain that a large part of this was deployed or tested on Dutch territory. Radar was used in various ways by the Air Force: to guide bombers to their target, to give the air defense "eyes and ears", for fire control and for combat control. The Navy used the on-shore radar to detect naval and air targets as well as fire control of coastal batteries and anti-aircraft batteries. Various command posts were set up in the hinterland for steering.   All types of radar known in our country, their locations and the command centers are described in the book. The collection of the former Bureau of Defense Works was mainly used as a source for the relevant buildings. These documents are located in the National Archives and are known as the "bunker archive". In the period shortly after the war, the Defense Registration Office was tasked with inventorying, measuring and describing the defenses that the occupying forces had built. From the more than 23,000 registered structures from the period 1940-1945, those buildings were selected, of which it could be established with sufficient certainty that they fulfilled a function for the purpose of radar. Allied and resistance espionage reports have also been used, which in some cases provided additional useful indications.
