Geometric Matching of Tracks from Several Radars and Estimation of Systematic Errors in Measurements *
نویسندگان
چکیده
Keywords: geometric matching, aircraft tracks, systematic errors of radars A problem of processing the measurements from air surveillance radars is considered. The measurements are provided by observation of air traffic. This processing aims at matching the tracks of aircrafts obtained by various radars and estimation of their systematic errors. The error estimates are built in the form of a " collection of corrections " for radars measurements. For finding estimates, redundancy of observations with data from several radars is used. In the approach suggested, neither one of radars is regarded as the reference standard in principle. The systematic errors are defined by combined procession of measurements from " neighboring " radars with overlapping observation zones.

The accuracy of airborne LiDAR has been a topic of research for many years, but there remains a need for a robust and reliable calibration technique. The accuracy of LiDAR points depends on various factors including GPS/IMU position and orientation, laser range, and scan angle measurements. As a result, the adjacent overlapping swaths, or flight strips, fail to match with each other. Surface ma...

The presence of systematic measuring errors complicates track-to-track association, spatially separates the tracks that correspond to the same true target, and seriously decline the performances of traditional track-to-track association algorithms. Consequently, the influence of radar systematic errors on tracks from different radars, which is described as some rotation and translation, has bee...
