Abstract : A low-cost (less than $1500) television type video tape recorder system was tested to determine whether the system could provide a recording of radar targets suitable for use in recreating air traffic situations. The equipment was evaluated in two modes of operation: (1) camera recording of the radar video from a scan-converted display; and (2) on-line recording of the radar video from the signal bus of a high-resolution scan converter. Although the mechanical performance of the system was adequate, its narrow bandwidth significantly degraded the resolution of the recorded display. Certain operational features were identified as further limiting factors. These features included tape running time, audio track capability, and automatic switchover features. In view of these limitations, it was concluded that the performance of the system was marginal for its intended use. It was recommended that the low-cost system not be adopted. (Author)
