In this study, a new approach is suggested about pattern correction due to the distortions by conformal situations in planar frequency diverse arrays (FDA). First, the differences of FDA systems from other conventional antenna array systems are evaluated and the pattern correction methods in the literature are discussed. Then, the technique of updating the inter-element frequency increment, which is a parameter of the array factor of the FDA system, is proposed in order to preserve the broadside radiation characteristic of the system and to compensate for the distortions in case the spatial coordinates change with external factors. Normally, the frequency increment between the array elements is constant and it must be much less than the central frequency of the system. Finally, the usability of the suggested technic is demonstrated with numeric examples.

Enine ışıyan düzlemsel ayrık frekanslı dizi antenlerde örüntü düzeltmede yeni bir yöntem

Öz

Bu çalışmada, düzlemsel ayrık frekanslı dizi anten sistemlerinde (Frequency Diverse Array-FDA) konformal durumlarda örüntüde meydana gelen bozulmanın düzeltilmesine yönelik yeni bir yaklaşım önerilmiştir. İlk olarak FDA sistemlerinin diğer geleneksel dizi anten sistemlerinden farklılıkları değerlendirilmiş ve literatürdeki örüntü düzeltme yöntemleri üzerinde tartışılmıştır. Ardından, harici etkenlerle uzaysal koordinatlarının değişmesi durumunda sistemin enine ışıma karakteristiğini korumak ve oluşan bozulmaları kompanze etmek için FDA sisteminin dizi faktörünün bir parametresi olan elemanlar arası frekans arttırımını güncelleme tekniği önerilmiştir. Bu parametre normalde sabittir ve merkezi frekanstan çok küçük olmalıdır. Son olarak önerilen yöntemin kullanılabilirliği nümerik örnekler aracılığıyla analiz edilmiştir.
