(U) In addition to the incidents on 10, ll, and l2 April described 1 in the initial UFO report, similar unidentified targets were observed on ~4 April. The targets were seen on eight occasions on the latter date, four times on both the search and precision rad:lr; in one i.nstance, four targets were visible simultaneously, and in another :in5tance , t .iO targets were present.

Evaluation of the Misawa AB, Japan, UFO Report indicates that the proba e cause was anomalous propagation. Radar echoes obtained from re- gions of the atmosphere where no apparent reflecting source exists, com- referred to as "angels," can usually be attributed to various causes; i.e., birds, insects, and meteorological effects. In this instance, the reported factors (range of target, speed, and no visual sighting) tend to support anomalous propagation. 2. Anomalous propagation occurs when the radiated radar beam is bent, by re ection or refraction, to the ground. The echoes return to the radar by the same path. The radar actually sees the ground or some object on the ground as a target. An apparent moving target is observed if the beam illuminates a moving object or even when the beam illuminates a stationary object on the ground if the reflecting portion of the atmosphere is itself in motion. It has been reported that at a range of 50 miles a horizontal reflecting layer rising 3 meters per second could cause an apparent echo to move at 300 miles per hour. This appears to be the only" likely technical explana~ion for the target speeds observed in this report. 3. Lack of ~angible evidence does allow the existence of other plausible causes. It is possible that spurious signals from airborne, shipborne or ground-based sources accidentally or intentionally caused the appearance of the seemingly nonexistent targets. However, as pointed out in Det 4, FTD letter (U) "Sup?le:nen~ to UFO Report," 4 May 1965, it is unlikely that two radars operating a c different frequencies would observe a false target, electronically generaced, in che same position. Consideration of the avail - able evidence, ho~ever, tends to supporc anomalous propagation as the cause. FRANK L.
