Research On Pattern Synthesis Algorithm For Arrays Antenna

In array design phase, with the mandate focus on the many factors to consider foregoing, the array calibre incentive to meet project to be sidelobes requirements and other requirements, that is often said in the synthesis of pattern . The synthesis of array pattern is by using one or more methods for antenna system design, enabling the system to produce the required pattern, the direction of good and just. It is the analysis of the anti-antenna design that, in a given pattern of array, the conditions for the design of radiation sources distribution for the pattern of the different applications and multiple changes.From this important purpose adaptive algorithms, genetic algorithms, control algorithms of sidelobes peak, null control algorithms for the four areas, the synthesis of array pattern is rather detailed researched here. Front-line and distance ranging from a uniform line array for the main study, in ideal conditions, respectively, conducted a study of four algorithms, and draw the corresponding conclusions.1. Adaptive algorithms. Adaptive antenna theory is that the direction of the antenna in the direction of interference generated zeros, if a direction from the array imposed interference through self addressed, the corresponding direction, the direction of the antenna array would reduce electricity ping. The application features, we will array to imagine a multi array applications. Based on SNR and LS guidelines, the two algorithms were examined in the main, the direction of the Sidelobes imposed interference adjustment array orientation map to meet design requirements. All while improving a multi algorithm, making it more in terms of reduction of more simple, taking into account factors arrays each pair to consider in the context of mutual mate can achieve design requirements, greatly expanded the relevance algorithm.2. Sidelobes peak control algorithms. Studied at the Sidelobes peak electricity Ping control iterative algorithms, based on the minimum criteria are to error, the only side petal peak electricity ping control, targeted to improve a...
