CSIR-NAL SPARCS: Software for RCS Prediction with/without RAS

CSIR-NAL SPARCS: Software for RCS Prediction with/without RAS

(SPARCS: Stealth Platform Asymptotic Radar Cross-section Software)

Key features:

  • Radar Cross Section Estimation Software using Hybrid Asymptotic High Frequency Methods (Geometric Optics, Physical Optics, SBR, UTD)
  • Precise and fast RCS estimation of analytical models
  • Parallelized numerical ray tracing based hybrid high frequency methods for RCS estimation of Complex Surfaces such as aircraft, UAV, missiles, ships
  • RCS estimation with/without radar absorber coating/structures (RAM/RAS)
  • Optimization of thickness profile of radar absorber towards payload reduction over broadband
  • Enhanced design capabilities with retro-design of existing platforms¬† ¬†

Software Validation Test Cases
