GPR Wavefield & Radargram Simulator (2D)

A genuine 2D finite-difference simulation of the georadar pulse itself: an electromagnetic wavefield propagates through a soil cross-section, reflects off a buried pipe and void, and the radargram is built trace by trace from the simulated field.

ControlsDrag the antenna position slider along the survey line (or toggle auto-scan) to fire simulated radar pulses at successive positions; adjust soil permittivity and buried-pipe depth to watch the 2D wave-equation solver propagate, reflect off the pipe and void, and build the radargram trace by trace.

This is the 2D counterpart to the Ground Penetrating Radar (GPR) Survey Simulator. Rather than rendering a 3-D soil block and computing reflector arrival times from a geometric formula, it solves the 2-D scalar wave equation on a grid representing the true position–depth cross-section beneath the survey line, letting the reflection hyperbolas emerge from a genuine simulated electromagnetic pulse bouncing off a buried pipe and a subsurface void. The radargram panel is assembled trace by trace directly from the simulated field, the same way real GPR forward-modelling software builds a synthetic B-scan.

⚙ Under the hood

Watch a real 2D finite-difference simulation of the ground-penetrating-radar pulse itself: an electromagnetic wavefield propagates through a soil cross-section, reflects off a buried pipe and a subsurface void, and builds the radargram trace by trace from the simulated field rather than a canned hyperbola formula.
