Abstract

To overcome the limitation of the real-time motion parameter estimation of flying target based on PLE(pseudo linear estimation)

a new algorithm for real-time estimating and tracking the motion parameters of flying target is proposed based on the measurement of flying target angle. The algorithm applies the Taylor series expansion to the angle measurement equation at the current flying target motion parameter estimation value

and the linear relationship between the estimated value of the current flying target motion parameter and the observed value of the angle is obtained. Then the estimations are updated by combining apriori maximum likelihood estimate of the flying target motion parameter and its error covariance matrix with bearing measurements

to iteratively estimate the flying motion parameters. Simulation results show that the proposed algorithm is fast

stable and effective

and is a real time processing mode in tracking system without a large amount of historical data storage. Its computational efficiency

compared with PLE

is increased by 50%.
