Martin Noretoft: Tracking based on double array configurations

The bearings-only target tracking problem is studied.
A simulation study is done to investigate the performance
of a solution to the passive ranging sonar problem.
Two different methods are compared.  One where the differences
of time delays between the sensors are measured and used for
passive ranging, and one where the submarine is towing a sonar
but do not use the information contained in the slightly curved
wavefront of the sound emitted from the target. An idea using
non-linear regression for the estimation is presented, but
not elaborated. The simulation studies will give some
indications about which of the variables, noise, distance
between the sensors, and  sampling time that give the biggest
impact on the quality of the estimation.
