One-dimensional Trajectory Correction Bomb Key Technology Research And Its Implementation

The use of precision and intelligent ammunition not only directly concerns the victory or defeat of the war but also can reduce the rate of civilian casualties. Trajectory Correction is one of the typical representatives. It is low-cost precision ammunition which reduces the firing errors, improves accuracy of the projectile firing by comparison of the ideal and practical trajectory, as well as finite discontinuous amendments to adjust the flight trajectory.This article focuses on the study of the system scheme, drag mechanism, communication systems and other key supporting technologies relate to the Trajectory Correction.The research is primarily reflected in:1. Propound a system scheme of the one-dimensional Trajectory Correction combining with our national conditions by analyzing the advantages and disadvantages of various trajectory correction approachs. It gives a detailed analysis of the ground system composition, missile-borne systerm composition principle and proposes a initial implementation plan of the actuating mechanism and the wireless communication system.2. Design a wireless communication system principle prototype include stuying the technical scheme of communication frequency communication protocol and data encryption , detailedly introducing the parts selection and hardware circuit design of the transmitting and receiving antenna ,transmitter and receive, communication system software architecture. In addition, it confirmed the feasibilit of the principle based on the experimental.3. Analy the deficiencies of the principle take improving measures to the relevant issues and design a premary prototype. In the premise of system requirements, it is more miniaturization and possesses good anti-interference ability.4. Determine the final design of the executive mechanism according to the simulation analysis and made a spin test.Conduct a progroud-combine debug and flight experiment, and analy the experimental data.Experiments show that the study of one-dimensional correction projectile subsystems such as ground radar and fire control systems, wireless communication systems and implementing agencies can realize reliable cooperative work. Communication system can achieve long-distance communication and transmission reliability. Missile-born receiver can withstand the high overload derive from the projectile's emission. Esistance organizations can successfully unlock after receiving instructions and achieve correction. This proves that the one-dimensional trajectory amendments mode of ground radar surveillance and progroud fire-control center control is entirely feasible and can achieve low-cost and miniaturization.
