ABSTRACT
The Active Sonobuoy Model simulates a single aircraft
attempting to detect and maintain contact on a single
submarine. The submarine executes a pre-determined sequence
of maneuvers upon counter-detection of the active sonobuoys.
Under present methodology these maneuvers are not situation
dependent, and do not provide an accurate depiction of
reality. The purpose of this thesis is to improve the level
of reality of the Active Sonobuoy Model through the
implementation of a set of situation dependent maneuver rules
for the submarine. This "smart" submarine is then compared to
the previously existing "dumb" submarine through the use of
hypothesis testing under two measures of effectiveness. The
results show that the "smart" submarine provides a more
difficult target for the aircraft to detect and sustain
contact with than the "dumb" submarine.

THESIS DISCLAIMER
The reader is cautioned that computer programs developed in
this research may not have been exercised for all cases of
interest. While every effort has been made, within the time
available, to ensure that the programs are free of
computational and logic errors, they cannot be considered
validated. Any application of these programs without
additional verification is at the risk of the user.
