lucernhammer MT is a fast, high-frequency (asymptotic) radar cross section (RCS) and signature prediction code. It uses a high-speed ray tracer and the shooting and bouncing ray (SBR) technique, augmented by edge diffraction.

Feature Details

• Monostatic and Bistatic complex-valued scattered far field and RCS.

• Supports ACAD facet and edge files directly without modifications.

• First-bounce Physical Optics uses direct facet-level integration with automatic polygon subdivision and high-precision ray tracer blockage checking. Blockage checking details are in the direct control of the user and can be adjusted to speed the run time.

• First-order edge diffraction using an automatic edge finding algorithm, or by reading an Xpatch-type edge file from disk.

• Multiple-bounce scattering calculations using the Shooting and Bouncing Ray method.

• Time-domain based fast SBR acceleration mode.

• Support for small surface features such as cracks and weld beads via Incremental Length Diffraction Coefficients (ILDCs).

• The user can enable or disable the PO, PTD, SBR, and ILDC calculations, and save their contributions to disk separately.

• Material support: Perfectly conducting (PEC) surfaces, thin layered dielectrics over PEC, fully penetrable (bulk) material regions, transparent materials, and absorbing materials.

• Supports multiple run-time geometry files, allowing the user to specify separately the pieces of a composite geometry or scene.

• Available for shared memory (SMP) as well as distributed memory systems (using MPI). Fully parallelized for multi-core systems.

• A high performance GPU-accelerated version is available for systems with one or more NVIDIA CUDA capable GPUs. Multi-GPU operation is fully supported.
