[0036] A method for intercepting an incoming air-to-air missile from the tail of an aircraft, such as Figure 1 shown.

[0037] Step 1: Detect the flight trajectory and guidance method of the incoming air-to-air missile.

[0038] Different aircraft can carry different air-to-air missiles, and different aircraft and air-to-air missiles have different signal characteristics, such as size, speed, maneuverability, radiation, and stealth characteristics. By identifying the signal characteristics of the enemy aircraft and the incoming air-to-air missile, the model of the incoming air-to-air missile can be determined more accurately.

[0039] A database of incoming air-to-air missile models is constructed. The database contains the corresponding relationships between different types of incoming air-to-air missiles and the signal characteristics of the opposing aircraft and the incoming air-to-air missiles. The flight trajectory of the incoming air-to-air missile is detected by the airborne detection system, and the signal characteristics of the opposing aircraft and the incoming air-to-air missile are detected and obtained. The incoming air-to-air missile model is compared with the database to determine the model of the incoming air-to-air missile, and then the guidance method of the incoming air-to-air missile is determined.

[0040] The airborne detection system may specifically include airborne radars, photoelectric detectors and other equipment, which can accurately sense the relative position and speed of the enemy aircraft, incoming air-to-air missiles and the aircraft in real time, as well as the signal characteristics of the enemy aircraft and incoming air-to-air missiles.

[0041] Step 2: Calculate the position information of the incoming air-to-air missiles at different times while the aircraft continues to fly stably, and determine the interception position.

[0042] Based on the detection of the flight trajectory of the incoming air-to-air missile and its guidance method, the onboard computer quickly calculates the position information of the incoming air-to-air missile at different times while the aircraft continues to fly stably, and selects the optimal interception position. The distance between the interception position and the aircraft should be greater than the damage radius of the explosion of the incoming air-to-air missile to ensure the safety of the aircraft.

[0043] Step 3: Fire a shell at the interception position and set the shell to explode at the interception position to form an interception barrier.

[0044] The onboard computer quickly calculates the direction and angle of the muzzle of the artillery shell launcher and the explosion time of the artillery shell required to launch the artillery shell at the interception position, and adjusts the direction and angle of the muzzle of the artillery shell launcher and sets the explosion time of the artillery shell accordingly;

[0045] The artillery shells are fired from an artillery shell launcher, the speed of the artillery shells is measured at the muzzle, and the explosion time of the artillery shells is corrected so that the artillery shells explode at the interception position to form an interception barrier.

[0046] The artillery shell launching device can adopt land-based anti-aircraft guns or ship-borne close-in defense guns. It is designed with the ability to quickly adjust the direction and angle of the muzzle, and has the ability of automatic loading and automatic firing. The speed of the shells can be measured at the muzzle and the explosion time of the shells can be set. The muzzle size is large and the barrel is short, and no rate of fire is required.

[0047] A high-toughness material is folded inside the shell of the artillery shell, and a detonating device is arranged in the high-toughness material. The detonating device can set the explosion time, and explodes at the explosion time to generate high-pressure gas to support the high-toughness material to unfold and form an interception barrier. Specifically, it can be designed to form a sphere with a radius of more than 1 meter. This kind of interception barrier has a low movement speed, a relatively static position, and a large size.

[0048] Steps 1 to 3 may be repeated to launch multiple shells toward the interception position, and the shells may be set to explode at the interception position to form multiple interception barriers. An ultra-large interception barrier may be constructed with a limited number of interception barriers.

[0049] Step 4: Detect the position of the incoming air-to-air missile and the interception barrier relative to the aircraft, adjust the aircraft's trajectory and attitude, guide the incoming air-to-air missile to collide with the interception barrier, and intercept the incoming air-to-air missile.

[0050] The onboard detection system detects the position of incoming air-to-air missiles and interception barriers relative to the aircraft;

[0051] The onboard computer takes over the aircraft's control authority, adjusts the aircraft's trajectory and attitude based on the guidance method of the incoming air-to-air missile, guides the incoming air-to-air missile to crash into the interception barrier, triggers the incoming air-to-air missile's fuse, or destroys the incoming air-to-air missile's body to complete the interception.

[0052] The high-toughness material may specifically be graphene material, and other available materials may also be selected according to actual conditions, so as to form an interception barrier that can effectively trigger the fuse of an incoming air-to-air missile, or destroy the body of an incoming air-to-air missile.

[0053] The above-mentioned embodiment discloses an interception method suitable for an incoming air-to-air missile from the tail of an aircraft. Aiming at the situation where an incoming air-to-air missile is attacked from the tail of an aircraft, the method is designed to guide the incoming air-to-air missile to collide with an interception barrier which is relatively stationary and has a larger size, so as to intercept the incoming air-to-air missile, change the confrontation between conventional missiles, and pursue the instantaneous spatial relationship between the interceptor missile and the incoming air-to-air missile. The design and implementation difficulty is relatively low, and it can well supplement the deficiency of the current aircraft in intercepting the incoming air-to-air missile from the tail.

[0054] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the scope of protection of the present application.
