Performance evaluation of track initiation in dense target environments

Performance analysis for the track initiation phase in very high target density environments is described. The analysis of tracking performance performed by S. Mori et al. (1989, 1990) yielded very simple expressions to predict average track purity in terms of tracking parameters. These results were, however, obtained mainly for the track continuation phase in which tracks are more or less well established. The authors extend these results to the track initiation phase. A linear approximation of the method which significantly simplifies the calculation is also presented. A simple test scenario, consisting of a threat object group and an orbiting sensor, was used to demonstrate the performance evaluation for track initiation
