Over-the-Horizon Detection of Multiple Aircraft: The Over-the-Horizon Detection of the Large-Scale Strategic Air Command Penetration Exercise (Snow Time 69-1-E) of 10 October 1968
Abstract
The Naval Research Laboratory OTH radar at NRL's Chesapeake Bay Division has been used to observe a large-scale simulated air attack on the east coast of the United States. Fifty-three aircraft, including B-52's and B-58's, were deployed at various altitudes and along continuously changing penetration corridors to accomplish the coastal thrust. The OTH radar was programmed to illuminate a selected area along the inbound routes, to permit the acquisition of the largest number of aircraft echoes over the term of the exercise. Multiple real-time detections were accomplished. Subsequent analysis has permitted track identification with post-exercise reported positions of 19 out of a possible 21 sorties. Definitive sorting has been accomplished with high resolution in velocity coupled with the doppler-time format of processing. Evasive maneuvers are particularly noticeable in the radar records. Such target behavior confirms sortie recognition. Analysis is continuing for aircraft detections that have as yet not been identified as a range-time track nor correlated with a particular sortie. Certain discrepancies between radar data and reported positions or maneuvers are being investigated.
