AMPLITUDE ANALYSIS PROGRAM
Abstract
The Amplitude Analysis Programs were written to produce an average pulse shape over a reasonable time interval for up to 200 range stations behind the tracked target leading edge and a frequency distribution of cross section at each station over the time period. The final output is presented as Stromberg- Carlson 4020 plots of average pulse and distributions. The input is obtained by digitizing A-Scope films on the Group 21 High Precision computer controlled film reader, filtering this data with a ramp filter to locate the position of the tracked target leading edge, and then writing a tape containing only that data behind the leading edge. The Amplitude Frequency Distribution and Statistical Program uses this filtered output tape and computes an average pulse and the standard deviation from this pulse at each desired range station over a given time interval and also finds the distribution of cross section at each range station, if desired. A tape containing this information is then used as input to the Amplitude Plotting Program which produces the Stromberg-Carlson 4020 plots. The present report contains a summary of the method of obtaining the input data, the mathematics involved, a description and listing of the two programs, and directions for running the programs.
