Embodiment 1

[0180] Taking the cooperative interception in two-dimensional plane as an example, the simulation research is carried out. Assuming that the interceptor and the penetration are chasing and intercepting, the penetration performs a constant acceleration (Constant Acceleration) maneuver, and the two interceptors are launched at the same time for coordinated interception. The simulation conditions are set as follows: the penetration acceleration is a EC =7m / s 2 , the initial distance from the two interceptors to penetration is 6000m, the initial line-of-sight angles are -0.3rad and 0.3rad, the initial line-of-sight angle rates are 0.03rad / s and -0.01rad / s, and the overload response time of the interceptors is 0.05s, the overload response time of the penetration device is 0.1s, the initial approach speed of the interceptor and the penetration is 400m / s; the objective function performance parameter a 1 、a 2 Both take 10 5 , b 1 , b 2 Both take 10 6 , c 1 、c 2 Both take 1, i...

Embodiment 2

[0184] When the penetration is performing a more intense sinusoidal maneuver, set the penetration command acceleration a EC =-70sin(πt)m / s 2 , interception angle Δ c1 Set to -45°, interception angle Δ c2 Set as 45°, all the other parameter settings are the same as those in Embodiment 1. Simulation results such as Figure 10-Figure 15 shown.

[0185] Depend on Figure 10 It can be seen from the motion trajectory of the aircraft shown that when the penetration is performing a more severe sinusoidal maneuver, the guidance law proposed by the present invention can also ensure that the interceptor maintains a good detection configuration during the whole guidance process, while the APN guidance law is in the process of cooperative interception. Interceptors are not guaranteed to achieve this effect.

[0186] Figure 11-Figure 12 It shows that the guidance law proposed by the present invention can ensure that the interceptor intercepts and penetrates at a predetermined line-o...

Abstract

The invention discloses a multiple interceptor collaborative detection and guidance integrated type intercepting method and system. On the basis of an aircraft relative motion relation and a double-sight collaborative detection error model, an interception model containing collaborative detection information is established; by taking intercepting miss distance, maneuvering energy consumption minimizing and effective modulation of an sight separation angle as control and optimization targets, a system performance constraint function is determined, and through system order reduction, and on thebasis of optimal control theory, an optimal guidance law is determined; and collaborative interception is carried out on a penetration device according to the optimal guidance law, and the optimal guidance law can ensure that multiple aircrafts has the collaborative detection effect in the collaborative guidance process. By adopting the intercepting method and system, the collaborative detection and guidance precision is improved, and meanwhile, the integrated design of multiple interceptors on the two links of cooperative detection and guidance is realized.

Description

technical field [0001] The invention relates to the field of cooperative detection and guidance of multiple interceptors, in particular to an interception method and system integrating cooperative detection and guidance of multiple interceptors. Background technique [0002] In recent years, with the continuous development of combat styles and aerospace technology, interceptors no longer have absolute maneuverability advantages over penetrators. At the same time, the concept of coordinated operations of multiple interceptors has received more and more attention. Compared with the traditional one-to-one interception method, the cooperation of multiple interceptors has great advantages in detection and guidance: on the one hand, the coordinated detection of multiple interceptors can conduct a more comprehensive and accurate measurement of the penetrator , which can effectively make up for the lack of a single interceptor in obtaining dynamic information for penetration; on th...
