Smoothing and Processing of Simulated Amrad Trajectory Data

摘要

In this report, an attempt is made to determine suitable smoothing intervals to be used in the smoothing of radar trajectory data. This is done by using different fitting intervals in the smoothing of simulated noisy trajectory data of different signal-to-noise ratios. The errors, or differences between the true noiseless data and the smoothed noisy data, were observed and plotted. Minimum errors were obtained when the range smoothing interval was approximately 1 to 2 seconds and the elevation and azimuth smoothing intervals 10 seconds. The plots suggest that elevation and azimuth errors can be further reduced by smoothing over intervals longer than 10 seconds but this would not be practical in many actual missile shots. (Author)
