Computer and analytic models of fighter intercept capability

This thesis describes a simulation model of fighter operations, and sets it in the context of a hierarchy of defence models. The fighter model is then applied to two problems which developed from an assessment of the contribution of sensors to the air defence of the UK. These concern the influence of raid indirect routing and sensor information accuracy on the intercept capability of fighters scrambled from ground alert. Mathematical models of these two aspects of fighter operations are also developed; this dual approach ensures that the studies are both analytically understandable and operationally acceptable. Examples are given of the number of fighters from a single base which could intercept a concentrated (point) raid against a single offset target . In the case of raid indirect routing the main variables are the angle of the incoming feint track and the warning distance. In the analysis of the effect of sensor information errors the main variables are the actual position of the raid when warning is given and the errors in raid coordinates, heading and speed due to degradation of the warning system. In both cases of indirect routing and information errors alternative scramble and control procedures are considered. The work described in this thesis is a step towards an attempt to determine the more favourable procedures which a fighter force might adopt in the face of subtle raid tactics and degraded sensor performance. It also provides an illustration of the interplay between mathematical methods and computer models in the analysis of fighter operations.
