Signa: A radar signature prediction tool for electrically large targets

This paper discusses the methodology and capabilities of a new computational electromagnetic (CEM) software tool for radar signature prediction, in addition to presenting initial validation results. Signa is a software tool based on the shooting and bouncing rays (SBR) method for rapid prediction and analysis of coherent radar cross section (RCS), suitable for use with various electrically large targets, including aircraft, ships, automobiles, and spacecraft.
