Abstract:

In this report it is assumed that a high-speed object generates a shock wave which is a right circular cone, and that the arrival time of the shock wave is obtained at various microphones. Arrival times are first calculated for a prescribed flight path, and then random errors are superimposed on the computer times to simulate experimental data. The speed and line of flight of the object are then determined from these data containing errors by using the method presented in NOLTR 68-33. This is done with a few different arrangements of the microphones. The errors in the calculated flight parameters are studied as a function of the errors that were introduced into the data. The calculation procedure is considered to be a feasible one to use in practice if satisfactory calculated results are obtained in spite of errors of an expected magnitude in the simulated data.
