Description

Delivery type interception net shield system and method for intercepting aerial targets Technical Field The invention belongs to the technical field of air defense and interception, and particularly relates to a delivery type interception net shield system and method for intercepting an air target, which are used for intercepting the active interception of a low-altitude, slow-speed and small-sized flying target. More particularly, the system is a modular, precisely deployable 'shield' type interception system that cooperatively delivers, deploys and maintains flexible interception meshes to form a directional defensive surface through multiple unmanned aerial vehicles, and integrates end-point destructive power. Background In the field of modern air defense, aiming at the large-scale threat of low-speed, small and low-cost targets such as unmanned aerial vehicles, the traditional point-to-point kinetic energy interception mode is difficult to be applied due to high cost and unbalanced efficiency-to-cost ratio. For this reason, the concept of implementing "face interception" using flexible interception nets has been developed with the aim of reducing the demanding requirements on single point hit accuracy by enlarging the effective interception area. The currently disclosed scheme of 'face interception' generally adopts aerostats such as balloons, airships and the like as a lift-off and bearing platform of an interception net. However, such schemes are limited by the fundamental characteristics of the core platform, and common problems of serious insufficient deployment precision are exposed in practical application, so that reliable and directional interception cannot be realized, and the following is specifically shown: 1. The lack of active and accurate delivery capability is that the horizontal movement of the aerostat is severely dependent on the ambient wind, and the flight trajectory has high uncertainty and hysteresis. This results in the whole system not being actively and cooperatively routed as a whole to a predetermined three-dimensional space interception point on command, nor being able to stay stably at the interception point, and tactical pre-deployment is not speaking. 2. The lack of stable, controllable defensive surface shaping capability-even upon reaching rough airspace, the aerostat platform lacks an active control mechanism that rapidly deploys the flexible barrier net and stably maintains a predetermined configuration (e.g., a plane or curved surface of a particular orientation). The net body is always in an uncertain state, a 'defending surface' with stable and reliable space position and gesture cannot be formed, and theoretical interception advantages are greatly weakened. 3. The platform does not have the capability of fast resolving, dynamic planning and unified scheduling of the whole system resources based on the real-time target track. The optimal interception point cannot be recalculated in real time after the target is maneuvered, the platform is instructed to adjust, the system is stiff, and the high-speed maneuvering target cannot be dealt with. In summary, the fundamental contradiction between existing aerostat-based intercept net systems is the attempt to use a passive, uncontrollable delivery platform (aerostat) to accomplish a tactical deployment task that requires an active, accurate, and fast response. The inherent defect of the platform layer can not convert the theoretical advantage of 'surface interception' into actual combat effectiveness, and the core bottleneck is the lack of an active delivery capability capable of stably and reliably delivering an interception net system to a preset airspace according to instructions. Disclosure of Invention 1. The invention aims to solve the technical problems The existing interception net system based on aerostats such as balloons, airships and the like has the defects that the delivery track is governed by wind power, accurate navigation and positioning cannot be realized, dynamic task requirements are difficult to respond, the interception net cloth is unstable in setting position, a reliable directional defense surface cannot be formed in preset time and airspace, and tactical efficiency is low. The aim of the present invention is to overcome the drawbacks inherent to the above-mentioned platforms and to provide a solution capable of actively, precisely and reliably delivering the interception net system to a predetermined interception point and stably stopping on command. 2. The technical proposal of the invention The invention provides a delivery type interception net shield system for intercepting an aerial target, which comprises a manufacturing unit, a flexible interception net body, an active delivery system, a defense surface forming system and a distributed damage unit. The active delivery system is composed of at least two unmanned planes with autonomous flight, positioning and networking communication function
