Abstract
Based on Crammer-Rao Lower Bound (CRLB), this paper adopts Geometric Dilution of Precision (GDOP) as the optimizing performance index to analyze the localization precision in Bearing-only localization for single observer. And the genetic algorithm is employed to calculate the optimal course sequence. The movement straight with constant velocity and movement with constant prefix angles are analyzed. Simulations show that maneuvering trajectory is propitious to improve localization precision.
