Simulated moving target indicator MTI radar imagery was used in the two experiments performed in this, one of an on-going series of studies in which we are investigating conditions of intermittent radar coverage. In the first of these experiments there were two, and in the second experiment there were two, three, or four consecutively-collected frames of imagery before each interruption in coverage. In both experiments there were twelve operators and the imagery was presented in time compression. The results of the two experiments showed that the use of more than one frame of imagery before the occurrence of the interruptions in radar coverage resulted in improved performance. For the larger, 25- and 50-vehicle units, two consecutively- collected frames, and for the smaller 10-vehicle units, four consecutively collected frames helped to prevent the decrement in tracking performance that otherwise occurred with 120-second interruptions.
