A Technique to Identify Certain Relative Errors in Radar X-Y Plots

摘要

An iterative analysis technique has been developed to identify two of the errors which frequently occur when two radars track the same target and record the information on separate X-Y plotters. Both a relative difference in starting points and a difference in speeds of the plotting arms along the abscissa axis can be identified. Once they are found, the relative errors can be eliminated easily. Application of this technique to computer-simulated data with known errors gave promising results. In each case the errors were identified, and each analysis required three iterations or fewer. The type of sampling used in the data had little effect on the accuracy of the analysis. When the technique was applied to balloon data obtained at White Sands Missile Range, New Mexico, the results were similar to the test data results. Good estimates of the two relative errors between the plots were found, with only two or three iterations required per sounding. (Author)
