The Reconstruction of Aircraft Target Trajectories from Historical Radar Plot Data

An algorithm which can accurately reconstruct an aircraft target trajectory from pre-recorded digital radar plots is described. Periodically recorded track data from a tracking system provide the coarse target position and speed estimates required by the algorithm. The algorithm has been applied in...

Description
Summary:An algorithm which can accurately reconstruct an aircraft target trajectory from pre-recorded digital radar plots is described. Periodically recorded track data from a tracking system provide the coarse target position and speed estimates required by the algorithm. The algorithm has been applied in the operational analysis of the RAAF AN/TPS-43F(V)-1 surveillance radar and Myriad tracking systems at the No.2 Control and Reporting Unit (2CRU), Darwin, using data acquired during exercise Pitch Black 84-1. It has proven to be reliable and effective in localising targets in the presence of clutter and system noise. Several trajectories obtained using the algorithms are illustrated and compared with the corresponding track data. Keywords: Great Britain.
