The effect of randomly missed range data on target tracking performance has been investigated. The specific problem addressed concerns SEAFIRE. Most of the development and results, however, are general enough to be extended to other purposes. Randomness of the missing range data was modeled as a first order Markov process while Singers correlated acceleration model was used to represent the target. Both of these models provide a quite general description of the stochastic processes being analyzed. The effect of uniformly non-random missed range data was also explored in order to provide a reference which is somewhat easier to analyze and understand. For the sake of completeness, angle tracking performance was briefly examined for the case of uninterrupted angle measurements. Results presented in this technical report are designed to aid in determining performance to be expected from a target tracking algorithm subjected to randomly interrupted range data and to aid in specifying sensor accuracy requirements necessary to obtain the desired tracking accuracy.
