Point info
– parameter values output: Trace number, Position, Sample number,
Time delay, Depth, specified profile’s point Amplitude, Latitude, Longitude and
Altitude as well as UTM Northing, Easting and Zone. If there is a mark its number will
be displayed in the bottom line of the dialog box. After activating
Point info
option
simply press anywhere on the profile where you need to know those parameters.
Holding left mouse button pressed will display a
Point Info
window illustrated in Fig.
10.2. Some of the information (trace number or position, sample number or time delay
or depth, latitude, longitude, altitude) is constantly displayed in the status bar located at
the bottom of the main window while you move your cursor along the profile.

Hyperbola
– Local object’s depth and medium’s permittivity determination.
When a profile intersects diffractive targets, such as pipes, cables, stones, archeological
objects, areas of drastic soil properties variation, their signals on the radiolocation
profiles have hyperbola shape; signal examples are shown in Figs. 4.2, 4.3, 10.3. When
Hyperbola
option tool is selected, pressing on the profile will draw hyperbolic line that
goes from a theoretical local target in a theoretically homogeneous medium, and open
an information window with this target and medium parameters. Your task is to match
the theoretical hyperbola with the signal’s hyperbola on the profile. First, align the
vertices of the hyperbolas; for this purpose, bring the cursor to the signal’s hyperbola
vertex, and press the left mouse button. The hyperbola slope may be changed by
pressing right mouse button: position the cursor on the signal’s hyperbola branch, and
press the right mouse button. For more accurate hyperbolas matching we recommend to
use
Zoom
in
on the Main menu (see below) and make several iterations. Matching
hyperbolas example is shown in Fig. 11.3.
Theoretical hyperbola’s line color may be changed in
