Estimation of aircraft altitude in 2D radar intelligence networking

An observation model of altitude estimation in 2D radar network with 2 sensors which is based on the WGS-84 ellipsoid earth is designed, and a new algorithm for target altitude estimation is presented. Through a lot of simulations and academic analysis, the performance of the algorithm is detailed analyzed. The simulation and analysis result shows that the algorithm accords to the fact of observation, makes full use of the observations, and the estimation of target altitude is improved.
