A track alignment-correlation algorithm with systematic errors in radar network

This paper has researched on the problem of track correlation with systematic errors in radar network, and analyzed that how does the systematic errors affect the detected tracks of target theoretically. On the basis, prior to registration, a track alignment-correlation algorithm based on Fourier Transform has been presented. The algorithm estimates the rotation and translation amount by using the Fourier Transform, and aligns the track data of targets reported by radars in the network, can correlate the track accurately without registration, and provide reliable correlated tracks for the next registration.
