KNOWLEDGE BASED AUTOMATIC THREAT EVALUATION AND WEAPON ASSIGNMENT SYSTEM FOR PAKISTAN AIR DEFENCE

Abstract

f an unassigned hostile enters the system, a threat index is computed. The threat index rates the hostile with respect to defended areas and, if a threshold is attained, a trial intercept calculation (TIC) is triggered. There may be several defended areas or the whole country could be considered as one large defended area. The TIC performed typically selects from a list of weapon resources (interceptors and surface to air missiles (SAM) for example), and recommends a set of weapons, ordered by the shortest time to intercept, to engage the target. The intercept problem solved by TIC processing is the time-space problem of placing the target and weapon at the same point in time and space. Once a TIC has been calculated against a target, the target is no longer evaluated as a threat, since a recommendation has been made to the operator, and automatic TEWA processing is terminated for the target. TEWA processing system should have the capability to process each zone parallel, and also our weapons should work parallel. And we should have to create the animation of our coming target. (Our system takes the threat input from the radar system, does processing on it and assigns it a threat index based on its distance from the border, speed, altitude and type of aircraft. Then it selects the targeted zone by updating zone table so that each zone can work parallel. Each zone calculates its trial intercept (TIC) for the target. Our system then sends the TARGET ID, WEAPON ID and TRIAL INTERCEPT POINTS to the controller which displays it and sends weapon free status to main server.)
