Abstract : Experimental investigation of interior ballistic events often requires a precise frequency spectrum analysis of data. This is particularly true in the study of high frequency pressure oscillations in the liquid propellant gun. Unfortunately, a phenomenon known as aliasing can severely bias the frequency spectrum of recorded data. In this report, aliasing is demonstrated with respect to regenerative liquid propellant gun data, and a standardized procedure is outlined to limit its effect.
