Target Motion Analysis

[Thomas D. Dean]

I have been looking at TMA using bearings only.  I found several (many?) 
papers on this, but, none seem to use geometry objects or provide code 
readily adaptable to octave.

I looked into using the Maple geometry package, but, ended up with a 
solution whose denominators had many zeros.

I thought of trying this with the octave geometry package, since the 
desired result is numerical, not symbolic.

The problem:  Obtain a series of bearings from the sensor to the target, 
where both may be maneuvering, changing both heading and velocity.

Known values are the sensor position at times t(0...n) and the true 
bearing from the sensor to the target.

Has this been done?

An alternate method of solving this problem is minimization but I have 
difficulties formating the problem.
