A New Satellite Passive Locating Algorithm Using Frequency-only Measurements Based on PSO
Yiyu Zhou · Journal of Astronautics · 2007
A new satellite to satellite passive locating algorithm using Frequency-Only measurements is proposed based on Particle Swarm Optimization(PSO).Firstly,the mathematic model of satellite to satellite passive locating is established.Secondly,the estimation method of the target satellite's orbital elements is proposed based on PSO.Thirdly,the corresponding Cramer-Rao lower bounds(CRLB) are then deduced.Finally,performance is validated through computer simulations.Simulations indicate that the proposed method is effective in terms of the estimation quality compared with CRLB and superior in computation burden to the grid search method.
