specific Embodiment

Specific examples:

[0088] This embodiment verifies the effectiveness of the proposed guidance law in three-dimensional coordination by using three interceptors to simultaneously attack maneuvering targets. The simulation initial condition of 3 interceptors and target in the embodiment:

[0089] Interceptor 1: initial position (1000m, 9000m, -2300m), initial speed (1100m / s, 100m / s, 100m / s)

[0090] Interceptor 2: initial position (500m, 8500m, -500m), initial velocity (1000m / s, 100m / s, 90m / s)

[0091] Interceptor 3: initial position (2000m, 7600m, 3000m), initial speed (950m / s, 60m / s, 110m / s)

[0092] Target: initial position (100000m, 8000m, 1000m), initial velocity (150m / s, 10m / s, 15m / s)

[0093] select Obviously (p xi ,p yi ,p zi ) is a positive real number greater than 0.

Abstract

The invention discloses a three-dimensional coordinated mid-guidance method for an air maneuvering target. The virtual collision point is used as the target point in the mid-guidance stage of the interceptor, and at the same time, the position information and speed of the target obtained directly through an external sensor during the mid-guidance stage are considered. Information and acceleration information design a coordinated mid-guidance method, and by adding cooperative adjustment items, it is ensured that all interceptors arrive at the mid-to-final shift transition area almost simultaneously at the end of the mid-guidance phase. The invention has the advantages of simple structure, clear physical meaning, easy understanding by engineering personnel, convenient adjustment of synergy item coefficient, strong guidance law robustness, etc., and easy engineering realization.

Description

technical field [0001] The invention belongs to the technical field of guidance, and in particular relates to a three-dimensional cooperative mid-guidance method. Background technique [0002] With the improvement of anti-interceptor technology, on the one hand, air maneuvering targets can interfere and counter interceptors by releasing decoys, snake-like maneuvers or other countermeasures, which greatly reduces the interception efficiency of existing interceptors; The performance of the target has been greatly improved with the rapid development of artificial intelligence and UAV technology. The detection and maneuverability of a single interceptor are difficult to meet the requirements of high-precision strikes, and coordinated encirclement attack technology is required. Therefore, the idea of ​​multi-interceptor cooperative penetration or interception came into being. Multi-interceptor cooperative formation cooperative combat means that multiple interceptors share inform...
