An AN/MPG-1 radar set picked up a fast moving low flying target

Target changing its elevation at an extremely rapid rate
 


               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.
