Do you have any information on the legacy codes DAGER and SABER?

DSIAC is searching for information on two legacy codes developed around 30 years agoDiscrimination Assessment for Generalized Engagement Response (DAGER) and Statistical Assessment of Beam Engagement Response (SABER).  DAGER and SABER are both used for system analysis of a neutral particle beam, directed-energy weapon for exoatmospheric ballistic missile defense.  The actual codes for DAGER and SABER are desired, as well as algorithm descriptions and (especially) the input files.

DAGER uses details from higher-fidelity models to generate the distribution of secondary emissions from an engaged target, the probability distributions of the likelihood of discriminating the mass of an irradiated target given a beam engagement condition, and sensor characteristics and the geometry of the beam-target-sensor configuration. Inputs include sets of files representing the secondary particles emitted from an interrogated target. These input files would normally be generated by high-fidelity codes run at facilities like Los Alamos National Laboratory, NM. Other inputs would likely include outputs from sensor response models.

SABER is an engineering-level code that generates the probability of kill distributions given a beam engagement condition from detailed threat object geometry and component fragility files. Inputs include target geometry files and fragility functions.

The input files may be classified at the SECRET RESTRICTED DATA (SRD) level.

If you have information on the owners or developers of the codes or input files, the repositories for the codes or input files, or past users of the codes, please discuss on the DTIC DoDTechSpace Forum and/or deliver directly to DSIAC via email.
