Wherein, Vdj1、Vdj2The flight speed of the airborne anti-ship missile and the flight speed of the ship-air missile are respectivelydThe response time of the ship-air missile system is determined, the set point W is the single-ship position for loading the ship-air missile system, and the point W is determinedfFor a single aircraft position, then LfIs a point W and a point WfHorizontal distance between the aircraft threat source and the single ship, Qf1For aircraft operating at radius, Qf2The maximum range of the airborne anti-ship missile is obtained; if the distance between the single-ship position for loading the ship-air missile system and the single-aircraft position is smaller than or equal to the maximum flight range of the airborne anti-ship missile, the single-ship aircraft missile anti-aircraft anti-guidance horizontal demand area of the single-aircraft threat source takes the single-ship position for loading the ship-air missile system as the center of a circle and has the radius RfThe circular area of (a).
3. The method according to claim 1 or 2, characterized in that: the region definition policy comprises:
if the threat source of the incoming attack is a single anti-ship missile threat source, further comparing the size relations between the distance between the position of the single ship carrying the aircraft-borne missile system and the position of the single anti-ship missile and the self-control distance and the self-guidance distance of the anti-ship missile respectively, namely determining an anti-aircraft anti-guidance horizontal demand region of the single-ship-free aircraft-borne missile if the distance between the position of the single ship carrying the aircraft-borne missile system and the position of the single anti-ship missile is greater than the sum of the self-control distance of the anti-ship missile and the self-guidance distance of the anti-ship missile; if the distance between the single-ship position for loading the ship-borne missile system and the single anti-ship missile position is greater than the self-guided distance of the anti-ship missiles and smaller than or equal to the sum of the self-control distance of the anti-ship missiles and the self-guided distance of the anti-ship missiles, the single-ship-borne missile anti-aircraft horizontal demand region of the single-aircraft threat source is the maximum distance R of the single-ship-borne missile anti-aircraft horizontal demand region based on the single anti-ship missile threat source by taking the single-ship position for loading the ship-borne missile system as the center of a circleaIs a horizontal sector area with a radius, and the angle of the horizontal sector area is based on a single anti-ship missile threat sourceThreat angle C of single-vessel aircraft missile air defense back guidance horizontal demand areaa，
Ra＝La+[td+La/(Vda1+Vda2)]Vda1，
Wherein, Vda1、Vda2The flight speed of the anti-ship missile, the flight speed of the ship-air missile and Qa1For self-control distance, Q of anti-ship missilea2Is the self-guiding distance of the anti-ship missile, LaThe distance between the position of a single ship for loading the ship-borne missile system and the position of a single anti-ship missile; if the distance between the single-ship position for loading the ship-air missile system and the single anti-ship missile position is smaller than or equal to the anti-ship missile self-guidance distance, the single-ship aircraft missile anti-aircraft anti-guidance horizontal demand region of the single-aircraft threat source takes the single-ship position for loading the ship-air missile system as the center of a circle and has the radius RaThe circular area of (a).
