Sdudy Of Precisely Control On Ballistic Correction System

Information and intelligence are the most important in the new century war. Precision strike munitions which are one of the hot directions that countries competing to develop. People first give an eye on missiles, precision guided missile indeed achieve the desired requirements, but its high cost is prohibitive for many countries in the other, so it can not get a lot of equipment. Thus giving rise to a vision of much another way in which trajectory correction projectiles is an ideal envisioned. As research on the trajectory correction countries, there have been many forms of implementation and posture correction technology. This study is use microwave as controlled signal to transform the way for shipboard artillery, which is an important development trend of naval equipment for shipboard weapons capability enhancement.The subject comes from "Twelfth Five-Year Plan” advanced manufacturing technology group pre-research project "tiny silicon substrate impedance structure processing technology", aiming at resolve the problem in the process of machining. The main content of this paper is based on the C-band impedance microstrip antenna array structured on the silicon substrate, based on the application of micro-electromechanical systems(MEMS) design and manufacturing technology, the demand for intelligent transformation of conventional ammunition for shipboard artillery projectile trajectory correction technology research and development to provide some theoretical basis. The main research work is divided into the following aspects:(1) Introduce existing development results of trajectory correction, according to the research situation, analyzed the features and feasibility of using microwave instruction control trajectory correction.(2) Study the feasibility of microwave trajectory correction system program. Based on a detailed analysis of system components, contrast land artillery trajectory correction technology achievements put forward the difficulties and problems in the shipboard artillery trajectory correction technology.(3) Analyzed the main factors affecting the accuracy of the shooting, the effects of the moving in the control system coordinates correction and surface wave microwave reflection signal interference and the impact of the tilt angle on ship, etc.(4) Designed the microstrip line filter and IF filter to meet the targets and considering the gun launch environment. Select other components to achieve reliable performance of microwave receiver.
