The development of high-tech with information technology as the core has greatly promoted the new military revolution in the world; Informatization is the essence and core of the new military revolution. As a typical information weapon, precision-guided weapons have been widely used in modern battlefields, and the proportion of precision-guided weapons used in the Iraq war has accounted for 68%. In recent years, major countries in the world have attached great importance to the research and development and procurement of precision-guided weapons, and precision-guided weapons have shown a strong development momentum; After the improvement and modification of the original equipment, the tactical and technical performance has been continuously improved, and new precision-guided weapons have emerged, which has made the precision-guided weapons have a comprehensive and diversified development pattern. In the new period and stage, it is of great significance to discuss the development trend of precision guided weapons for studying the confrontation mode and combat style of information warfare and gaining the initiative of information warfare. ?
1 Integration of launch unit, guidance system and operational information platform of precision guided weapons to improve overall operational efficiency?
In the future information war, no matter what form of war is adopted, it is required to find the target quickly and accurately, make timely decisions and strike accurately. Information warfare is not only the informationization of command and control system, but also the informationization of weapon system. As a typical information weapon, precision guided weapons should not only obtain information from their own detectors, but also make full use of various information resources on the battlefield. The existing launch unit of precision guided weapons is improved by informationization, so that it can fully support C4I, C4ISR, C4KISR and other command and control systems, and realize information sharing, so that the launch unit can not only have its own fire distribution data, but also * * enjoy the comprehensive intelligence data of superiors, so as to * * enjoy the enemy's frontier terrain, layout, weapons and equipment, etc. It provides necessary support for combatants to master the launch timing of precision guided weapons or to automatically correct parameters before launch. At present, the degree of information acquisition and utilization of precision guided weapons is not high, and the sensors on missiles are close to detect and are easily disturbed. Moreover, due to the limitation of volume and mass, the detection performance of the sensor on the missile can not be compared with other detection platforms. If the data link is added to the precision-guided weapons, information can be shared between the precision-guided weapons and between the precision-guided weapons and other information platforms through the data link, so that the maneuvering and environmental changes of the target can be quickly detected, data exchange can be carried out in flight, and the data on the missile can be corrected in real time, which will greatly improve the detection distance and detection accuracy, and can also identify specific targets and evaluate the damage to the targets. If the original target is destroyed, the guidance system can re-select a new route to attack the replacement target. At the same time, the data on the missile can also be transmitted back to the command and control information platform through the data link, and the commander can evaluate the damage situation according to the data returned by the data link and attack the most vulnerable area of the target, thus significantly improving the operational efficiency. Through the data link, ground troops or unmanned reconnaissance aircraft can also be used to guide and attack maneuvering targets or difficult-to-find targets. At present, the US military is working hard to develop air patrol ammunition, which can stay in an area until it attacks the target as instructed. ?
In the future anti-tank operations, the anti-tank detachment will be equipped with a relatively perfect C4KISR system, so that all combat units can share information and communicate with each other. The anti-tank weapon system will use photoelectric information and computer technology to collect, fuse, process, transmit and display battlefield information in real time, and realize comprehensive tasks such as launching, control, attack and shooting effect evaluation, and finally realize networking, automation and real-time. The anti-tank detachment can not only make full use of the battlefield information collected by the anti-tank weapon system itself, but also fully enjoy the operational information provided by its other weapon platforms and C4KISR system. It can obtain and process the information of target type, distance, azimuth and quantity in near real time, make a quick decision and distribute it reasonably, use a variety of anti-tank weapons and a sufficient number of anti-tank weapons to strike together, and evaluate the damage effect in near real time to carry out a second attack, thus making the operation. ?
The development of new guidance technology, multi-mode guidance technology and intelligent terminal guidance technology will greatly improve the hit accuracy and anti-jamming ability of precision guided weapons.
Disturbance ability?
At present, new guidance technologies such as infrared (mid-far infrared) homing, infrared imaging, laser semi-active homing and laser beam steering, active/passive radar homing (focusing on millimeter wave), optical fiber guidance, computer optimal control, star positioning and so on are constantly developing; The successful application of these new guidance technologies in precision-guided weapons will make a qualitative leap in the guidance accuracy of precision-guided weapons. Many new guidance technologies, such as laser guidance, infrared imaging guidance and millimeter wave guidance, have been applied to precision guided weapons. These new high-precision guidance technologies improve the guidance accuracy of missiles by an order of magnitude. ?
The new technology is not perfect, and any guidance system has certain limitations in use. Due to the influence of detector performance and environment on missiles, the detection distance of precision guided weapons is limited. Multi-mode composite guidance technology can work in different frequency bands (infrared, ultraviolet, visible light, microwave, broadband microwave, millimeter wave and so on). ) and different working systems (active, semi-active, passive, command, etc. ). Some precision guided weapons adopt the compound mode of mid-terminal guidance, in which satellite navigation CPS/ Strapdown Inertial Navigation is the main guidance technology, and in the terminal guidance, staring infrared imaging and millimeter-wave broadband high-resolution imaging are the main guidance technologies. Multimode seeker is the most widely used seeker in the world. At present, the main types of dual-mode seeker are: optical dichroism, microwave/infrared and millimeter wave/infrared imaging; Infrared imaging and millimeter wave active are the important development directions of multimode composite guidance technology at home and abroad, and it is expected to maintain a good development momentum in the future 10. ?
With the rapid development of artificial intelligence technology and its successful application in precision guided weapons, precision guided weapons will not only have the ability to automatically attack targets, but also have the ability of logical judgment, reasoning and identification, and become the most intelligent weapons and equipment in the world. In particular, the breakthrough of information fusion and recognition processing technology in data-level fusion processing makes the target information obtained by each sensor realize intelligent recognition processing, which not only can accurately hit the target, but also can carry out multi-target selection and adaptive anti-jamming when carrying out attacks; When choosing a hit target, it can automatically find the most vulnerable and critical part of the target to obtain higher operational efficiency. ATR technology is the focus of intelligent information processing. The new generation infrared image ATR system is programmable, integrated with artificial intelligence, and has adaptive and learning ability. In addition, it should be pointed out that artificial neural network is being applied to ATR technology. Although ATR technology has not yet reached the practical level, it has made great progress, which will certainly drive the development of intelligent information processing technology with precise guidance.
