Least squares estimation techniques for position tracking of radioactive sources

  title={Least squares estimation techniques for position tracking of radioactive sources},
  author={James W. Howse and Lawrence O. Ticknor and Kenneth R. Muske},
This paper describes least squares estimation algorithms used for tracking the physical location of radioactive sources in real-time as they are moved around in a facility. We present both recursive and moving horizon nonlinear least squares estimation algorithms that consider both the change in the source location and the deviation between measurements and model predictions. The measurements used to estimate position consist of four count rates reported by four different gamma ray detectors… CONTINUE READING
