【Abstract】 For the single sensor target tracking with bearing-only measurement,a novel trajectory invariable-information target tracking algorithm is proposed.A new cotangent theorem is deduced to solve the nonlinearity for bearing-only measurement.Both the heading angle calculation and the invariable-information of target trajectory are deduced to estimate the target bearing.For asynchronous bearing-only measurements from multiple sensors,a new two-sensor-with-bearing-only measurement target tracking method is brought forward,which estimates the target position by the geometry between sensors and target.Simulation results show that the new algorithm achieves a favorable tracking precision.更多还原
