Abstract:

This paper introduces the single observer passive location of the fixed target of radiation sources,stations with the goal to achieve fast ranging and positioning relative tangential to the the movement azimuth rate of change and the rate of change of pitch angle,and analysis of the measured parameters,positional parameters on the positioning accuracy,draw a positioning accuracy of geometric distribution (GDOP) of this positioning method algorithm simulation analysis.Simulation results show that single-ranging positioning relative error as the distance increases,after repeatedly observed multiple time instantaneous positioning results of its statistical filtering processing to improve locate and track conditions,reducing the positioning errors.

Key words: passive position technology;vertically moving;variety rate of angle
