1.  On 10 September 1951 an AN/MPG-1 radar set picked up a fast moving

          low flying target (exact altitude undetermined) at approximately 1110 hours

          southeast of Fort Monmouth at a range of about 12,000 yards.  The target

          appeared to approximately follow the coast line changing its range only

          slightly but changing its azimuth rapidly.  The radar set was switched to

          full aided azimuth tracking which normally is fast enough to track jet air-

          craft, but in this case was too slow to be resorted to.  The target was

          lost in the northeast at a range of about 14,000 yards.  This target also

          presented an unusually strong return for an aircraft being comparable in

          strength to that usually received from a costal ship.  The operator ini-

          tially identified the target as a ship and then realized that it could not

          be a ship after he observed its maximum speed.

               2.  On 10 September 1951, 1515 hours, ********** serial number ******

          tracked a target which moved about slowly in azimuth north of Fort Monmouth

          at a range of about 32,000 yards at the extremely unusual elevation angle of

          1350 mils (altitude approx. 93,000 ft).

               3.  On 11 September 1951, 1050 hours, two SCR-584's, serial numbers 217

          and 315 picked up the same target northeast of Fort Monmouth at an elevation

          angle of 350 to 300 mils at a range of approximately 30,000 yards.  (approxi-

          mate altitude 31,000 ft)  The sets track automatically in azimuth and eleva-

          tion and with aided range tracking are capable of tracking targets up to the

          speed of 700 mph.  In this case however, both sets found it impossible to

          track the target in range due to its speed and the operator had to resort to

          manual range tracking in order to hold the target.  The target was tracked

          in this manner for the maximum tracking range of 32,000 yards.  The operator

          judged the target to be moving at a speed several hundred miles per hour

          higher than the maximum tracking ability of the radar sets.  This tar-

          get provided an extremely strong return which at times even though it was at

          maximum range, however the sets signal occasionally fell off to a level

          below normal return.  These changes coincided with maneuvers of the target.

               4.  On 11 September 1951 at about 1330 a target was picked up on an

          SCR-584 radar set serial number 315 that displayed unusual maneuverability.

          The target was approximately over Navesink, New Jersey as indicated by its

          10,000 yard range, 6000 ft altitude and due north azimuth.  The target re-

          mained practically stationary on the scope and appeared to be hovering.

          The operators looked out of the van in an attempt to see the target since

          page two

          it was at such a short range, however overcast conditions prevented such

          observation.  Returning to their operating positions the target was ob-

          served to be changing its elevation at an extremely rapid rate, the changes

          in range were so small the operators believed the target must have risen

          nearly vertically.  The target ceased its rise in elevation at an elevation

          angle of approximately 1500 mils at which time it proceeded to move at an

          extremely rapid rate in range in a southerly direction and once again the speed

          of the target exceeding the automatic tracking ability of the SCR-584 so that

          manual tracking became necessary.  The radar tracked the target to the maxi-

          mum range of 32,000 yards at which time the target was at an elevation angle

          of 300 mils.  The operators did not attempt to judge the speed in excess

          of the aided tracking rate of 700 mph.

               5. The weather was fair when observation was made on 10 September

          and cloudy for the 11 September reports.
