Problems solved by technology

The defense difficulties of hypersonic vehicles are mainly reflected in the following aspects: first, the flying speed is fast, which puts forward high speed requirements for interceptors; The aerodynamic force can maneuver laterally, and it can also do jumping flight; the third is that the detection is more difficult, the background of the adjacent space space is a complex ionosphere, there are a large number of cosmic rays and electromagnetic radiation, and the detection environment is complex
Traditional interception methods are difficult to effectively intercept targets such as hypersonic vehicles

[0020] Specific implementation mode 1: The method for analyzing the handover conditions of hypersonic target interceptor missiles based on interception geometry described in this implementation mode is implemented in accordance with the following steps:

[0021] 1. By considering all possible speed directions of the target, and according to the relative motion relationship between the interceptor and the target, deduce the positions of all possible hit points, and establish the interception geometry;

[0022] 2. According to the research results of the interception geometry and the positional relationship between the interceptor bomb, the target and the interception geometry at the transition time of the intermediate and terminal guidance, the interception conditions to be met for the interception of the hypersonic target are given;

[0024] Specific embodiment two: the difference between this embodiment and specific embodiment one is: in step one, the established interception geometry process is as follows:

[0025] In order to simplify the problem, the movement of the interceptor and the target is regarded as the particle movement in the same fixed plane, which is called the attack plane. To get the coordinates of all possible hit points, first consider the case of a single hit point. Assume that the interceptor missile M and the target T are both flying in a straight line, and the speeds are v M and v T , the hit point in this case is point I, such as figure 2 shown, and will figure 2 The triangle formed by the medium interceptor, the target and the hit point I is called the interception triangle.

[0026] Assuming that the time taken by the target to move from the initial position to the hit point is T, then

[0027] the s T =v T T (21)

[0028] The time taken by the interceptor bomb to move f...

specific Embodiment approach 3

[0059] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: in step two, the specific process of deriving the interception conditions to be met by intercepting hypersonic targets is:

[0060] The transition conditions of the mid-to-terminal guidance of the interceptor missile studied in the present invention include position conditions and angle conditions, and the position condition refers to the scope of the position coordinates allowed at the time of transition of the mid-to-terminal guidance for the interceptor bomb to successfully intercept the target or meet the specified miss amount requirements , the angle condition refers to the range of the ballistic inclination angle allowed by the interceptor missile at the transition time of the mid-to-terminal guidance.

[0061] It can be obtained from formula (7) that when the speed ratio γ Figure 5 shown.

Abstract

The invention provides an analysis method of handover conditions of a hypersonic-velocity target interception missile based on interception geometry and belongs to the field of aircraft manufacturing technology. The method is technically characterized in that by considering all possible velocity direction of a target and according to the relative motion relation between the interception missile and the target, positions of all possible impact points are obtained through derivation, and the interception geometry is built; according to a research result of the interception geometry and the positional relation among the interception missile at the midcourse and terminal guidance handover moment, the target and the interception geometry, interception conditions required to be met for intercepting the hypersonic-velocity target are given; on the basis that the interception conditions are met, a calculation method of the positional condition and the solving process of the angle condition of the interception missile at the midcourse and terminal guidance handover moment are given, and the influence of maneuvering of the target on solving the angle condition of the interception missile is analyzed. Through the method, the problem that the hypersonic-velocity target cannot be intercepted through an existing interception method is solved.
