The Maneuvering Target Statistical Tracker, developed by Daniel H. Wagner
Associates in the early 1980's, was chosen by Navy as a Standard
Tracker for at-sea targets. It is now used in many tactical data
systems, including the Global Command and Control System (GCCS)
and Tomahawk Weapons Control System (TWCS). It is the primary Gaussian tracking
model for our advanced data fusion products.
| We initially developed the tracking program MTST
(Maneuvering Target Statistical Tracker) in 1980 for COMSUBPAC.
It uses a maneuvering target motion model (the Integrated Ornstein-Uhlenbeck
process) and accepts both bearing and position observations.
It also accounts for the navigation error of the sensor. The
key features which distinguish the current version of MTST from other such tracking
programs are that it models lines-of-bearing as a sum of Gaussian
distributions, produces estimates for the target's history
(based on all of the data-before and after the time of estimate)
as well as the target's current state, and that it makes provision
for identifying and rejecting outliers in the data set. |

Versions exist for MTST in multiple computer languages. We have
also developed many new extensions for passive tracking and other
unique problems.
