Abstract

Radar kesit alanı (RCS), modern hava silah sistemlerinin tasarımı ve performansında kritik bir faktördür. Bu sistemler, düşük profilleri, gelişmiş hüzme oluşturma ve açı ölçüm yetenekleri nedeniyle faz dizili antenleri yoğun bir şekilde kullanmaktadır. Faz dizili antenlerin platform RCS'si üzerindeki etkisi önemli olabilir. Faz dizili antenlerin RCS'si ele alınırken hem yapısal hem de anten modlu saçılma ile başa çıkmak gerekir. Her bir bileşen, hesaplama için benzersiz zorluklar sunar ve özel azaltma teknikleri gerektirir. Bu kısa inceleme, anten ve yapısal mod RCS'si hesaplamasına yönelik çeşitli mevcut yöntemlere değinmekte ve bu yöntemlerin uygulamalarına dair bilgiler sunmaktadır. Büyük dizi antenlerinin RCS simülasyonu, yüksek hesaplama kaynaklarına olan talepler nedeniyle önemli zorluklar sunar. Bu inceleme, RCS modellemesinde simülasyon sürelerini ve bellek kullanımını azaltmaya yönelik mevcut çözümleri vurgulamaktadır. Ancak, büyük ölçekli dizi antenlerinin daha verimli ve doğru bir şekilde simüle edilmesi için daha fazla ilerlemeye ihtiyaç vardır.

A Complementary Overview and Challenges in Radar Cross Section Modeling of Phased Array Antennas

Abstract

The radar cross-section (RCS) is a critical factor in the design and performance of modern airborne weapon systems. These systems utilize phased array antennas due to their low profile, advanced beamforming, and angle measurement capabilities. The effect of phased array antennas on platform RCS can be crucial. Addressing the RCS of phased array antennas involves solving both structural and antenna mode scattering. Each component presents different challenges for computation and requires specific RCS reduction techniques. This short review delves into various existing methods for computing antenna and structural mode RCS and offers insights into their application. Simulating the RCS of large array antennas presents significant challenges due to the high demands on computing resources. Additionally, this review highlights existing solutions aimed at reducing the simulation times and memory usage in RCS modeling while maintaining accurate results. However, further advancements are necessary to simulate large scale array antennas more efficiently and accurately.
