was being used in connection with the maintenanee operation. (There is no mention
of this in the report, however.) Also, the report
to rotate the antenna to a new bearing to determine whether the signal originated
inside the equipment. ( (This question arises since the azimuth of the target was
reported to be exactly the same throughout the time of interception and, therefore, :
appears to indicate that the antenna was not rotating.) Further, regular operating
personnel are generally more familiar with the appearance of a particular radar
Hence, it is concluded that possibly a false target due to equipment malfunction
rather than an actual target caused the reported radar paint.
