New method of war field situation assessment in air defense confrontation

Problem of war field situation assessment is deeply studied from the view of operation commanding. Firstly, a novel definition to war field situation is given, and the concept of air attack situation and air defense situation is presented. The factors of influencing situation are divided into two parts, one part is static factors, another part is dynamic factors. The index system of static factors and dynamic factors that influences the air attack situation and air defense situation is given. Then a new technique of determining factor denotation value is put forward, it distinguishes the factor denotation value from the factor attribute value, and it defines that denotation value is the subjection degree of attribute value relative to fuzzy concept. Lastly, a war field situation assessment model based on hierarchical decomposition of fuzzy concept is built. The above mentioned achievement has been applied in C3I systems, and provides support for commander to hold the war field situation and battle process.
