Examples on landmine models-regarding

[Santhu Athidi]

Hello all,

We want to simulate some landmine models using gprMax like PMA, PMD, PMN etc.. Please give some references and some '.in' example files. Thank you in advance.

The landmine models are not available in the current release of gprMax. They will likely be included in the next major release which will be towards the end of 2022/beginning of 2023.

Kind regards,

Craig

Are these models available now in end of 2024? How to develop new models?

Hello all,

I’ve modelled a scaled replica of the Adrushya (Mine II) in gprMax and simulated it under various environments. The scaling was done because the original landmine size produced excessively strong reflections in the simulation domain, so I reduced the dimensions to achieve more realistic reflected signals.

Original landmine (real):

• L×W×H: 330 × 240 × 140 mm

• Body: ~10% GRP (polycarbonate)

• Liner: Copper

My scaled model (in gprMax):

• Cylinder: R = 60 mm, H = 40 mm

• Sphere: R = 40 mm

• Box 1 (center): 105 × 120 × 40 mm — Filling: PEC

• Box 2 (bottom): 60 × 120 × 30 mm

• Materials: εr varied 2–4, σ = 0 S/m

Questions:

1. Is there an existing gprMax model for Adrushya / Mine II (with copper liner / GRP body) that I could compare with?

2. Any quick suggestions to improve the realism of my current model (liner, composite body, or materials)?

I’m also attaching images of both the original landmine and my modelled version for better understanding.

Thanks in advance,
Moloy
