CLARA identifies four functions: Data Space Generator, Truth Data Generator, Coefficient Generator, and Reconstructor. Together these four functions standardize the solution to the LAR problem. This ICD defines the logical interfaces of the four functions. This document specifies the CLARA interfaces of the Data Space Generator, Truth Data Generator, Coefficient Generator, and Reconstructor functions as shown in Figure 1. The weapon and delivery platform developers define the details of each function.
In response to a U.S. Air Force Executive Weapon Systems Review (EWSR) Task Group (TG) charter, the Society of Automotive Engineers (SAE) Common Launch Acceptability Region (LAR) Approach (CLARA) TG produced this Interface Control Document (ICD). The EWSR recognized the expensive nature of the present multiple-LAR development approaches and sought help from the SAE to standardize and document a new common LAR approach that is less expensive and time consuming. The EWSR TG recommended key characteristics upon which to base the new approach. This ICD is based on those key characteristics.
