Abstract: Aiming at the key index requirements for airborne fire control radar equipment in typical combat-level air confrontation scenarios, this paper studies an airborne fire control radar operational requirement model covering radar detection, tracking and guidance capability indicators. A typical airborne fire control radar combat-level air confrontation scenario and operational requirement sample set are constructed. Based on the mapping relationship of radar requirement indicators, radar operational effectiveness evaluation factors are designed, and radar operational effectiveness evaluation and requirement index optimization with normalized expert weighting are carried out. The large-sample scenario verification of radar requirement indicators is realized, which can provide effective digital simulation technical reference for constructing accurate system requirements in the requirement analysis stage of airborne fire control radar equipment development.
