Fuse wide beam forming method and system based on forward detection beam width index

Abstract

The invention provides a fuse wide beam forming method and system based on a forward detection beam width index. The method comprises the steps of S1, building a forward detection beam boundary mathematical model through encountering section missile and target relative position and angle geometric analysis under a preset intersection condition; S2, analyzing the forward detection beam boundary change trend to obtain a intersection condition corresponding to the maximum value of a forward detection beam boundary; S3, inputting the intersection condition corresponding to the maximum value of the forward detection beam boundary into the forward detection beam boundary mathematical model, and calculating to obtain a forward detection beam width value; and S4, according to the calculated forward detection beam width value, setting the guidance integrated fuse forward detection beam width index, completing fuse wide beam forming, and ensuring that the target head is always in a fuze forward detection beam range under a preset intersection condition.

Description

technical field [0001] The present invention relates to the technical field of integrated guidance fuze, in particular, to a method and system for forming a wide beam of a fuze based on a forward detection beam width index, and more specifically, to a fast calculation method for a forward detection beam width. Background technique [0002] The ultra-high-speed targets that appeared in the early stage had a small maneuvering force, and the anti-orbit interception method was often used when the missile was attacked. Directing the detection beam can ensure the continuous detection and tracking of the target by the guidance integrated fuze. With the emergence of hypersonic targets with variable ballistic maneuvers, the difficulty of reverse orbit interception has been greatly increased, and larger rendezvous angles and larger missile attack angles will appear in the missile-target encounter segment. Under the conditions of high relative speed, large rendezvous angle, and large ...

Problems solved by technology

When the relative speed is high (such as the relative speed is greater than 5000m / s), the narrow beam tracking method requires a high beam tracking rate (for example, a beam tracking rate of at least 150° / s is required when the relative speed is 5000m / s), according to the current technology hard to accomplish

If the wide beam assignment method is used, it is necessary to set a reasonable forward detection beam width of the fuze; the detection beam width is too small to ensure that the target is always within the range of the fuze detection beam under the given rendezvous conditions, and the fuze may fail to detect the target Phenomenon: The design of the detection beam width is too large, and the operating distance cannot be increased. There may be problems such as the lack of response of the triggering system and difficulties in the coordination of the triggering, and the phenomenon that it cannot cause effective damage to the target.

[0003] According to domestic and foreign literature review, there are very few studies on the calculation of forward sounding beam width
