Defense of hypersonic vehicle with ADS-B/AIS load near space
- 2019-03-08-

ADS-B/AIS Load near SpaceHypersonic vehicles fly at high frequencies, with no fixed tracks, and can fly in orbit as well as in the atmosphere. In the case of suborbital flights or flights within the atmosphere, the altitude of the flight is precisely between the flight of traditional aerial vehicles and ballistic missiles, which is also the current defensive gap between air defense weapons and anti-missile weapons, it is difficult to implement effective interception, and its ballistic and drop point is difficult to predict, can not constitute an effective interception conditions, Therefore, it has stronger penetration performance than ballistic missile and subsonic cruise missiles. Therefore, the proximity space hypersonic vehicle poses a serious challenge to the existing air defense anti-missile system according to the available information, the larger threat of the approaching space hypersonic target flight airspace is concentrated at about 30km height. Because of the proNear Space ADS-B/AIS loadThe spatial span is large, the radar characteristic of the target, the optical characteristic, the speed characteristic, the flight airspace and so on are different from the traditional aircraft class target, so it is necessary to use various technical schemes to intercept. Anti-missile interception is generally used for hypersonic weapons, which may become one of the development trends of hypersonic targets in the anti-proximity space.

1. Early warning detection system

RightADS-B/AIS Load near SpaceHypersonic targets, early radar detection and discovery are the first conditions for interception. When the target enters the interception airspace from about 30km high, the detection distance of the ground radar is required to be 930km. Due to the limitation of the Earth's curvature, it is difficult for a single ground-base radar to detect, detect and track targets at that distance. Specific measures could be taken as follows:

A) The use of space-based early warning satellites, space-based early warning radar and other detection equipment, at this time detection early warning system can be compatible with anti-aircraft anti-missile system;

B) The use of networked detection guidance technology to network terrestrial radars or to place radar on floats and to be connected to other weapons systems;

C) The use of space-based satellite detection, tracking high-speed targets, ground radar front deployment, ground and sea radar shipborne early warning aircraft relay to intercept the target information, forming a three-dimensional detection network in the defense zone.

2. Command and control system

Reverse Proximity Space Hypersonic Vehicle command and control system should be able to effectively and dynamically connect, manage and process different information resources, distribute battlefield data in a timely and effective manner, realize firepower reorganization, resource sharing, rapid decision-making, ensure remote warning and tracking of targets, and provide fast and high precision target information for intercepting weapons.

Specific measures include:

A) Establish a networked command and control system that comprehensively processes data from other collaborative units in the interception system to achieve firepower control throughout the system;

B) The use of information raster technology, the realization of multi-sensor, multi-source information fusion processing, so that each sensor in the time domain, frequency domain, airspace effective and consistent work;

C) The use of Flat command and control mode, directly receive the real-time target information provided by each detection system for rapid decision-making, rapid allocation of targets, operational effectiveness evaluation.

3. Interception of weapons systems

The adjacent space Vehicle Interceptor Missile is a new type of weapon after the anti-aircraft anti-missile weapon, its technical characteristics are closely related to the adjacent space vehicle, and the technical ways of intercepting the weapon system at present are as follows:

A) The use of multistage booster mode, in order to obtain higher flight speed at the same time reduce the quality of takeoff, easy to combat use;

B) The use of aerodynamic/posture rail control composite control technology, the formation of a strong maneuvering overload capacity and the flight process of a larger trajectory correction capacity;

C) using the high parabolic end subduction and the target rendezvous, the active radar seeker is adopted to ensure the end long-distance composite guidance shift and the precise guidance interception of the target.
