occurred on June 6, 1944. It was the day that Allied forces stormed the French coastline with overwhelming numbers
of battleships, landing craft, bombers, fighters, and personnel. It broke the German stronghold on mainland Europe
and marked the beginning of the end of Hitler's dominion. These photos are the first official releases of radar
imagery before and during the D-Day
* invasion at Normandy. Pre-invasion
reconnaissance radar plots show a sparsely populated coastline and English Channel. White areas that indicate radar
targets were concentrated mainly in city regions. On the day of the invasion, white returns nearly saturate the
displays due to the incredible presence of all the aforementioned war machine elements. Even the soldiers' presence
contributed to the return because of all the metallic hardware being carried - guns, ammo, radios, helmets, bayonets,
canteens, etc. Less than a year later, on May 8, 1945, the Western world was celebrating what is now known as
(Victory in Europe).

Radar Plots the Invasion
By Eugene Mason
for the first time historical radar photos of the Normandy beachhead invasion. Radar has proven to be the greatest
technical development of this war.
Fig. 1. Normandy beaches looked like this in the radar scopes of Eighth Air Force bombers during the pre-invasion
reconnaissance flights. Despite solid clouds, coastline and built-up areas of the various towns showed up clearly.
Radar's most extensive use is to portray sea and ground formations far beneath high-altitude bombers and reconnaissance
planes. Scanning the earth with its electronic beam, radar draws accurate maps of the land and sea beneath the plane
- despite darkness, clouds, or rain. Shown here, for the first time, are actual pictures seen by radar operators
in their oscilloscopes, miles above the French coast before and during the European invasion. Every dot or blur
of white has some significance in understanding a radar scope picture, because each dot of white indicates an object
on the ground reflecting the radar pulses. Thus large cities show up brighter than the surrounding countryside.
White dots in the English Channel are boats, ships, or low-flying aircraft. Small dots visible inland usually indicate
man-made structures. The brilliant white blotch in the center of these pictures shows the position of the plane
when the photograph was taken. Concentric circles indicate the range from the plane. The Normandy beaches looked
quiet and peaceful (Fig. 1) during a pre-invasion reconnaissance flight. The cities of Le Havre and Cherbourg are
clearly visible in the scope. And the characteristic French seacoast is strongly etched. The same beaches on D-Day
(Fig. 2) look much different. Every dot on the oscilloscope represents one or more invasion craft in the Channel.
A few of the white blobs represent planes flying low over the water. Seen from a height of many miles, the radar-equipped
plane was about 35 miles from the French coast, its position indicated by the brilliant center spot. Strong elements
of the invasion fleet are massed just off shore. But in every direction can be seen the great mass of sea and air
power thrown into the D-Day offensive. The radar-equipped plane has passed over the invasion fleet (Fig. 3) and,
at a lower altitude, is about to cross the coastline. The plane, on a bombing mission ahead of the newly established
bridgehead, will use radar to locate strategic military objectives. Even though the pilot and bombardier can see
nothing, the radar operator can tell them where they are. Before crossing the coastline, the radar operator flips
a switch on his set to obtain a greatly magnified picture (Fig. 4) of the actual bridge-head. The many white dots
and blurs - though difficult to distinguish near the center of the scope - are clearly discernible as invasion barges,
boats, and ships. These are historic pictures - tiny white blobs of light on the face of an oscilloscope that attest
to the might of Allied sea and air power.

has moved to within thirty-five miles of the coast. Its position indicated by bright spot in center of scope.
Invasion fleet (smaller blobs and grains) is clearly visible massed just off shore. Fig. 3 (center). Even though
pilot and bombardier can see nothing. Radar operators can tell them just where they are and when to drop their
bombs. The photograph shows that the plane has lust passed over the invasion fleet and is about to cross the
coastline. Fig. 4 (right). Radar operator has turned a switch to obtain a magnified exact picture of a small
part of the coastline.
