Based on the above design, the present invention will be described below by taking specific examples as examples:
the method comprises the following steps of (1) defining a single-warship-to-air missile air defense and reverse guidance horizontal demand area based on a single aircraft threat source:
first, threat level areas of individual aircraft threat sources to individual vessels are defined: when an aircraft attacks a single ship, the aircraft usually first goes from point W f Flight distance Q f1 Reach point E f Then at point E f Launching anti-warship missiles to attack single warship, wherein, the point W is the single warship position of the loading warship-to-air missile system and is shown in figure 2 f Straight line WJ for single aircraft position f Is a horizontal datum line, L f Is point W and point W f Distance, Q f1 For aircraft combat radius, Q f2 The maximum range of the airborne anti-ship missile; point E f Is the intersection point of two circular arcs, the circular arcs are respectively in point W f As the center of a circle, take Q f1 A first arc formed by radius and Q with point W as center f2 A second arc formed for the radius; point W f1 Is a straight line WE f With point W as centre of a circle and L f An intersection point of a third arc formed for drawing an arc for the radius; horizontal sector W f WW f2 Horizontal sector W f1 WW f Is a sector plane which is symmetrical with each other,both take the point W as the center of a circle and take the straight line WW f As the central axis, take L f Radius, point W f2 Is a horizontal sector W f WW f2 Is defined by the boundary points of the respective frames.
Secondly, based on the parameters, the threat level area definition of a single aircraft threat source to a single ship needs to be divided into the following three conditions:
(1) In case one, when L f >Q f1 +Q f2 When the aircraft threat source does not threat the single ship, the threat level area of the aircraft threat source to the single ship does not exist.
(2) In case two, when Q f2 <L f ≤Q f1 +Q f2 When the distance from the aircraft to the distance point W is required to fly to be less than or equal to L f Can launch the anti-ship missile after the position of the anti-ship missile; the threat level area of the aircraft threat source to the single ship is centered on the point W and L f Radius, initial orientation B, end orientation B+C f Is a horizontal sector W of f1 WW f2 Wherein, the method comprises the steps of, wherein,

Finally, after the threat level area of the single aircraft threat source to the single ship is defined, the single ship air missile air defense reverse conduction level requirement area based on the single aircraft threat source is defined: referring to fig. 2, a ship-to-air missile anti-air-return horizontal demand area based on a single aircraft threat source is an area determined by considering the flight speeds of an airborne anti-ship missile and a ship-to-air missile and the reaction time factor of a ship-to-air missile system on the basis of the threat level area of the aircraft threat source to the single aircraft.
Correspondingly, the definition of the single-warship air-borne missile air defense and reverse guidance horizontal demand area based on a single aircraft threat source is divided into the following three conditions:
in case one, when L f >Q f1 +Q f2 When the aircraft threat source is not in a threat level area of the aircraft threat source to the single warship, the single warship air missile air defense reverse conduction level requirement area based on the single aircraft threat source is not in existence.
In case two, when Q f2 <L f ≤Q f1 +Q f2 When the distance from the aircraft to the distance point W is required to fly to be less than or equal to L f After the position of the carrier-to-carrier missile is launched, the single carrier-to-carrier missile air defense and reverse conduction horizontal demand area based on the single-frame aircraft threat source takes a single carrier position point W of a carrier-to-air missile loading system as a circle center, and the single carrier-to-carrier missile air defense and reverse conduction horizontal demand area maximum distance R based on the single-frame aircraft threat source f Horizontal sector area W of radius f3 WW f4 The angle of the horizontal sector area is a threat angle C of a single-warship-to-air missile air defense and reverse guidance horizontal demand area based on a single aircraft threat source f ，

In case three, when L f ≤Q f2 When the plane is at point W f The anti-ship missile can be launched, and the single-ship air missile anti-air-defense anti-guiding horizontal demand area based on the single aircraft threat source is formed by taking point W as the center of a circle and R f Is a circle of radius.

in case four, when L a >Q a1 +Q a2 When the single anti-warship missile does not have threat to the single warship, a threat level area of the anti-warship missile to the single warship is not present.
Case five, when Q a2 <L a ≤Q a1 +Q a2 At point W of anti-ship missile a Threat can be formed to the single warship, and the threat level area of the threat source of the single anti-warship missile to the single warship takes the point W as the center of a circle and takes L as the threat level area a Radius, initial orientation B, end orientation B+C a Is a horizontal sector W of a1 WW a2 Wherein, the method comprises the steps of, wherein,
