The program provides a simulation of the magnetic response from a total field gradiometer over a target defined by preset values or by the user. The purpose of the program is to use graphical displays to highlight the recorded magnetic response from a buried target for a given set of gradiometer separations, survey speeds and sampling separations. The displays include graphs showing the magnetic response from two total field sensors and the transverse or vertical gradient, a side and plan view of the survey geometry with vector arrows showing the direction of field or with an amplitude colour chart. A table of model values is presented and gives useful values calculated by the program.
This program has two wizards to explain the different aspects and features of the program. The simple wizard uses the program’s predefined targets and basic survey options to give quick results for standard surveys, while the advanced wizard uses more complex options and gives more detail about the individual input fields. Also, it leads you through the process of defining your own targets. On the completion of these wizards, the results will be shown in the main program and gives access to all the adjustable parameters. There is an option to skip the wizards and go straight to the main program if you wish.
