Array Millimeter-wave Phased Antenna Radar Seeker Technology Research

Radar seeker combined with millimeter wave band and phased array antenna system has the characteristics of millimeter wave high accuracy,anti-jamming and flexible beam steering of phased array.It is a very important research area for precision strike weapons in the future.Therefore,phased array radar seeker technology needs to be developed to enhance radar seeker's ability of target tracking and tracking in complex electromagnetic environment,we apply it to the coast defense missile guidance system,and research phased array radar seeker technology in the field.The research of millimeter wave phased array radar seeker technology is carried out,which lays a solid foundation for reliable scanning,detection and tracking of ship targets under complex electromagnetic conditions.Designed to have high caliber radiation power product,excellent dynamic response ability,array space division multi beam,high precision of angle measurement and tracking performance of the advantages of the active phased array technology scheme;study the general design scheme of millimeter wave phased array radar seeker by phased array antenna,intermediate frequency,signal processor and extension two times the power of four parts;the design describes the functions,technical index system,work flow,structure layout design;complete millimeter wave phased array radar seeker angle tracking distance measurement accuracy,three indicators of accuracy and distance are analyzed,which meet the design requirements.This thesis focuses on the design of radar guided seeker phased array antenna,phased array array beam control and T/R components,three key technologies are discussed,including planar array technology using array analysis;completed the design of phased array antenna beam width,EIRP and G/T are three important indicators,meet the design requirements.Finally,the experimental test verification is carried out by using the prototype of the prototype designed and studied,and the results of the test are compared and summarized.Through the research of millimeter wave phased array radar seeker technology,three key technologies,phased array,T/R module and beam control,have been conquered.The test of sea surface performance has been completed.Millimeter wave phased array radar seeker overall design and prototype technology research based on the experimental results,the performance index is expected to reach,that can meet the performance requirements of sea surface using millimeter wave phased array radar seeker,verified based on millimeter wave phased array antenna radar seeker is correct in principle,feasible scheme.If the application of engineering,will be able to improve the combat capabilities and radar of anti-ship missile attack hit probability,enhance efficiency,can improve the missile cost-effectiveness,will lead the future development direction of the field,including anti-ship.
