Abstract :
We have devised a system to automatically detect, manage and track contacts with a stationary line array. The array has a large number of elements, and the ability to process any subset of these elements (up to a fixed number) at any given time. Detection is accomplished by fixed detection apertures spaced along the array such that the apertures create a "tripwire" range parallel to the length of the array. Contacts crossing the tripwire range are handed off to an automated tracking aperture which adjusts its aperture size and aperture center along the array to track the contact using the best subset of elements. The adaptive detection scheme conserves limited tracker resources by limiting the trackers to those contacts which appear to be heading towards the line array. This system has been implemented on a Mercury Adapdev system and has been tested using simulation of multiple approaching contacts with interfering distant contacts
