Abstract

In this paper, a hybrid model is developed, which can estimate scattering properties of a target embedded inside a forest. The model uses a physic-based channel model for a forest to accurately calculate the penetrated field through a forest canopy. The channel model is based on a fractal tree geometry and single scattering theory. To calculate scattering from the target physical optics(PO) is used to compute an induced current on the target surface since the dimension of the target is generally very large and the shape is very complicated. Then using reciprocity theorem, scattering generated by the PO current is calculated without an extra computational complexity.

이 논문에서는 숲 속에 숨어있는 타겟의 산란 특성을 계산할 수 있는 효율적인 모델을 계발한다. 이 산란모델은 숲의 산란 특성을 계산하기 위해 프랙탈 기하학과 single scattering 이론을 사용하는 channel model과 타겟 자체의 산란 특성을 계산하기 위해 physical optic(PO) 근사법을 사용하는 hybrid 모델이다. 그리고 전체 모델의 계산량을 줄이기 위해 가역정리를 사용하여 간단하게 타겟과 숲 사이의 상호 작용을 계산한다.
