Low-cost interception system for low-altitude low-speed small target and interception method

Abstract

The invention discloses a low-cost interception system for low-altitude low-speed small targets and an interception method. The interception system is composed of a vehicle-mounted multiple launchingsystem, a multi-target detection and position indication radar, a data transmission ground end, a ground command and control system and interceptor missiles. The interception method comprises the steps of target detection and position indication, task allocation and interceptor missile launching, interceptor missile initial guidance, interceptor missile task route updating and middle guidance, automatic target acquisition by an interceptor missile image seeker and terminal guidance, interceptor missile fuse action and warhead detonation for target damage. According to the system and the method, the multiple interception targets can be subjected to detection and position indication through the multi-target detection and position indication radar, and the interceptor missile is electricallydriven, can fold and unfold airfoils, and is carried on a strapdown image seeker and a navigation and flight control system, so that the interception cost can be greatly reduced under the condition that the interception precision is guaranteed; and meanwhile, due to the fact that the flying distance of the interceptor missile is long, and the air route middle guidance is adopted, the coming targets can be intercepted at a long distance.

Description

technical field [0001] The invention belongs to the technical field of aircraft interception, and in particular relates to a low-altitude, slow-speed and small-sized target low-cost interception system and an interception method. Background technique [0002] "Low, slow and small" targets usually refer to aircraft with a flight altitude of no more than 1000m, a flight speed of no more than 200km / h, and a radar reflection area of ​​no more than 2m2. It has the characteristics of low cost, mature technology, and small target characteristics. With the maturity of UAV technology and the popularization of UAV products for various purposes, "low, slow and small" aircraft are very easy to obtain and operate, and are constantly being used by lawbreakers and hostile forces to carry dangerous items such as explosives to perform various tasks. Attack and sabotage activities, especially when multiple "low, slow and small" targets attack a specific target at the same time in a group atta...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to effectively deal with "low, slow and small" targets, a variety of interception technologies have been developed, including short-range air defense missiles, high-energy lasers, anti-drone jamming guns, net bombs, and high-energy microwaves. Among them, short-range air defense missiles are the traditional interception methods. The cost of single-shot interception is high; the interception distance of high-energy lasers is relatively short, which requires high accuracy of ground tracking and aiming, and cannot intercept multiple targets at the same time; the interference distance of anti-drone jamming guns is short; , It is difficult to intercept large-sized targets; high-energy microwaves require large energy and short interception distances
