Fig. 8. Sequence of vertical radar profiling (VRP) processing to extract up-going reflections from data collected 31 Mar. 2003: (a) data after dewowing and static shift for instrument time-zero; (b) corrected for statics computed on first arrivals; (c) reflection enhancement via residual median filtering; and (d) reflections double corrected back with statics from first arrivals. From (d) the depth of the reflecting horizons can be read at the intersection between the corrected first arrival curve (black line) and each reflected event. Note that each reflection is represented by several peaks and troughs because of the wavelet of the radar signal. Uncertain reflectors are shown with a question mark.
