Abstract

Bu çalışmada yapay
açıklıklı radar görüntülerinin oluşturulmasında kullanılan yöntemlerden,
Uyumlanmış Filtre, Geriye-İzdüşüm ve w-k algoritmalarının görüntü oluşturmadaki
performansları karşılaştırılmıştır. Kıyaslamada çözünürlük,  işlem süresi, sinyal-gürültü oranı,
sinyal-karışıklık oranı ve tümleşik yan lop oranı gibi parametreler dikkate
alınmıştır. Algoritmalar hem benzetim verilerine hem de 14- 18 GHz bandında
ölçülen gerçek yer-bazlı yapay açıklıklı radar verilerine uygulanmıştır. Elde
edilen sonuçlar, hangi tekniğin amaçlanan hedef için daha yararlı olduğu
konusunda karşılaştırmalı veriler sağlamaktadır.

Comparison of the synthetic aperture radar imaging algorithms

Abstract

In this study, the performances of the matched filter, back-projection and w-k algorithms used in the reconstruction of the synthetic aperture radar images are compared. In the comparison, the parameters such as resolution, processing time, signal-to-noise ratio, signal-to-clutter ratio and integrated side lobe ratio are considered. The reconstruction algorithms are applied to both simulation data and real ground-based synthetic aperture radar data measured in 14-18 GHz band. The obtained results provide comparative data on which technique is more useful for the desired purpose.
