Abstract : This follow-on report compares the performance of the adaptive nonparametric multisensor track initiation (ANMSTI) algorithm to that of conventional M out of N (MIN) track initiation algorithms, for a test set composed of concurrent radar and infrared search and track (IRST) data. To present a fair comparison of the various techniques, both false track initiation rates and track initiation times are analyzed in this report. While the analysis shows that some of the M/N techniques provide better track initiation times than the ANMSTI approach, some of these same techniques have false track initiation rates that in cluttered environments render them almost useless. Furthermore, it is shown that the ANMSTI algorithm is capable of regulating its false track initiation rate, whereas the M/N algorithms cannot. When comparing the time to first track initiation of single sensor and dual sensor M/N techniques, most of the benefits of using a dual sensor M/N track initiation criteria are shown to accrue when the track initiation criterion is relatively strict (i.e., usually when false alarm rates from the sensors are high).
