First, the basic Decentralized Square Root Information Filter DSRIF theory was extended in 2 ways. An expression for the likelihood function in terms of DSRIF variables, and a method for distributing the prior and process noise statistics over the set of locally optimal filters were derived. Next, software developed in Phase I research was upgraded to enable multitarget tracking within our distributed filtering environment. Outlier detection rejection, track initiation, measurement-to-track and track-to-track association routines were encoded and successfully tested using real MLRS data provided by WSMR. Finally, MTI conducted experimental work wherein 2 video trackers were built and networked with a global processor. Laboratory testing showed that the 2-camera network could track a variety of objects over the entire laboratory space. Moreover, each tracker was able to aid the other in acquiring a common target. Field testing of an individual tracker showed that it could acquire and track objects similar to the SADARM submunition, and against a cloudy background.
