Abstract: A comparison of shock waveform reconstruction techniques is made with synthetic signals in this program. A Friedlander pulse is synthesized in time, numerically integrated to obtain a projected signal, mapped to space, deconvolved in three different ways, and mapped back to time. One reconstruction technique is based on the Abel inverse integral transform, and two others are based on an inverse integral transform that directly reconstructs the fluctuating refraction index field from velocity data, i.e., a projection of the fluctuating refraction index field's time derivative. Reconstructed waveforms are plotted, errors quantified on a sample-by-sample basis, and errors quantified for pulse parameters such as positive peak, negative peak, and positive phase duration. Software was coded in Python 3.7. Journal article citing use of this software: https://doi.org/10.1121/10.0024520
