A system and method for decentralized cooperative control of a team of agents for geographic and other search tasks. The approach is behavior-based and uses probability particle approach to the search problem. Agents are attracted to probability distributions in the form of virtual particles of probability that represent hypotheses about the existence of objects of interest in a geographic area or a data-space. Reliance on dependable, high-bandwidth communication is reduced by modeling the movements of other team members and the objects of interest between periodic update messages.

System and method for automated search by distributed elements

A phased array antenna system in accordance with the present invention is configured to transfer signal energy between an antenna array and a source/target via multiple subbeams respectively carried in different frequency channels. Each antenna array element can thus receive a composite signal which can be band pass filtered to separate the different frequency channel signal components. By separating the signal components, a different phase taper can be applied to each signal component thereby enabling coherent signal energy to be derived from each antenna element. The derived signal energy can then be combined to produce an antenna input/output signal.
