Abstract
In an active multistatic sonar setup, multiple sensors are used for localizing a target by comparing the direct and target-echoed energy of transmissions originating from a number of acoustic sources. Source and receiver position inaccuracies being unavoidable, a question of interest relates to the effect of such inaccuracies on the precision of the multistatic localization. In this publication, a geometrical technique is proposed for bounding from above the multistatic target-localization uncertainty resulting from inaccurate asset positions. The proposed schemes only require a few user-inputs and the most computer-intensive results can be pre-computed off-line. Moreover, the present treatment is generic in that it applies to any source-target-receiver configuration confined to a finite region. Examples illustrate that the resulting upper bound is tighter and better conditioned for degenerate cases documented in the existing literature.
