A Kriegsmarine were in the process of building a heavy detection station consisting of a Mammut Fu.MO 51 device on a V143 bunker.
Fu.Mo - Funkmess-Ortung, Radar - direction finder, active ranging.
Interesting I search as much as I can to find detail and this is what I found:
"Even a simplified listing of radar type designations, with their technical particulars, would require a intensive research in German and foreign archives". Says it all.

Bunker type is a V143 Mammutstand, a multi roomed bunker to hold a large radar array. This type just sent out a large beam, imagine it being dark and you switch on a light switch. When a ship/aircraft passed through it. A shadow would show up. Very like the British Chain Home radar. It could not sweep the sky like the more modern types.

AIR 40-1667 Rhubarb - Appendix XII Coastal Radar Stations
Information
Wn346 Les Asselins la Gouinerie, Omoville la Rogue
Details
Allied plan of the radar site. Rhubarb was the RAF's code name for German radar attacks. Some of the sites were bombed by heavy bombers but others were attacked by bomb dropping and rocket firing Typhoons.
Near the Hameau des Asselins lies the most interesting of German bunkers.
This is a rare Mammut radar installation (named Gouesneraie), used not only
for detecting shipping, but it also gave the range for the guns to either side of
it. The bunker is quite a rare V143 type of which only four were built. The
Mammut radar was called hoarding by the British, because of its size and
shape. It sat on three huge concrete pillars sitting on top of the bunker. It was
a long range radar having an effective range of 300 kilometers, and it gave an
incredible accuracy in its findings. The cables that linked the antenna to the
electronics below in the bunker can still be seen. There were two entrances to
the control centre, both protected by machine gun posts. Inside the condition
of the bunker is good and none of the heavy metal doors have been taken for
scrap. None of the equipment remains as all radar and electronic equipment
was taken for further use by the liberating Americans. The floor of many of
the internal rooms show just how much thought went into its construction.
Cable ducts and special walkways were formed into the concrete, much as you
would have found in a computer during the 1960's. You can see evidence of
the taking of the radar station by the Americans on the left hand entrance. by

Details
Known as '30 Assault Unit', they took part in the major campaigns of the Second World War, landing on the Normandy beaches and helping to liberate Paris. 30AU's final amazing coup was to seize the entire archives of the German Navy - thirty tons of documents.
Although this was the American sphere of influence 30AU came here to Asselins to look over the bunker for any technical information. They were a mix of Commandos and Naval Officers with a Troop of Commandos to add muscle. They took the Naval HQ in Cherbourg, visited all the sites on Manche and then went into Brittany.

AIR 40-1667 Rhubarb - Appendix XII Coastal Radar Stations
Information
Wn346 Les Asselins la Gouinerie, Omoville la Rogue
Details
RAF Bomber Command file on radar targets, the secret designation for radars was Rhubarb. In his very informative book, "Most Secret War" RV Jones writes about going to RAF Typhoon Squadrons and talking to the pilots about the radars and then asking them to attack them one at a time. A bit like "Putting the lights out". The pilots kept asking why they were not allowed to attack a certain radar in northern France. RV (as he was known) kept telling them "No leave it alone". Well D-Day happened and the Fortitude deception plan used that radar to see fake images coming from small ships with radar reflectors, several bomber squadrons dropping Window, radar reflecting materials. These spoofs completely fooled the German intelligence service. The day after D-Day, RJ visited the squadron and told them, OK get the Radar. They literally ran to their planes, jumped in and went out and completely smashed the place.
