Abstract


In modern warfare environment, increasingly intensive electromagnetic signals , electronic interference and attacks are more brutal . How to destroy the enemy in the war to save themselves, is an urgent problem . Since there is no radiation -radiation missiles , has a hidden , anti- interference ability and role of electronic distance and other characteristics, in modern warfare has a strong vitality and practical significance , since its inception has been so much attention . Passive anti-radiation missile radar seeker as an integral part , has also been a focus of research . This paper analyzes the various measurements of the antenna system to a different system requirements . As to the practical application of the method of measuring a wide range , each of the antenna system with the corresponding requirements. Through a variety of measurements to the system as well as a variety of systems to meet the different requirements of finding a common antenna performance compared to determine suitable for passive seeker antenna system . Secondly, the analysis of the passive seeker physical structure of an antenna selection scheme . Directly determines the physical structure of the antenna of the antenna radiation characteristics of the various passive seeker can meet the operational needs of the selection of parameters and therefore the structure is very important . By analyzing the various parts of the antenna on the antenna performance, choose suitable parameters for the passive job seeker in HFSS established a specific model and simulation , to obtain a more satisfactory result. Third , for the general configuration of Archimedean spiral antenna is in the practical application of the deficiencies of the two measures for improvement . These measures can effectively improve the radiation characteristics of the antenna , so that the Archimedean spiral antenna can be better adapted to the actual needs. Fourth, as the main task of the passive seeker , passive localization has been highly regarded research. This positioning method for passive and passive location algorithm is analyzed and discussed. Kalman algorithm is the most studied of an algorithm , the simulation found that , taken to its improved algorithm can be obtained more quickly and accurately positioning results . Finally, a summary of the full text , outlines the research results.
