본 논문에서는 X-밴드의 XNUMX중 편광 SAR(Synthetic Aperture Radar) 데이터를 이용하여 벼 생육의 계절적 변화를 이해하기 위한 편광 산란 특성을 조사합니다. 여기에서는 모델로부터 쿼드 편광 SAR 데이터를 얻기 위해 X 밴드 주파수의 무향실에서 단순화된 벼 모델에 대한 편광 산란 측정을 수행합니다. 측정은 계절변화에 따른 벼의 성장단계별로 여러 차례 실시하였다. 모델 기반 산란력 분해는 논벼 모델의 편광 특성을 조사하는 데 사용됩니다. 측정자료에 대한 편광 SAR 영상분석 결과, 벼의 식재방향뿐만 아니라 정상이지만 레이더 방향에 비스듬합니다. 또한 방향각 보상(OAC)이 경사 식재의 경우 식물 후기 성장 단계 관찰의 정확도를 향상시키는 데 유용하다는 것을 알 수 있습니다.

Abstract: In this brief paper, we examine polarimetric scattering characteristics for understanding seasonal change of paddy rice growth by using quad-polarimetric synthetic aperture radar (SAR) data in the X-band. Here we carry out polarimetric scattering measurement for a simplified paddy rice model in an anechoic chamber at X-band frequency to acquire the the quad polarimetric SAR data from the model. The measurements are performed several times for each growth stage of the paddy rice corresponding to seasonal change. The model-based scattering power decomposition is used for the examination of polarimetric features of the paddy rice model. It is found from the result of the polarimetric SAR image analysis for the measurement data that the growth state of the paddy rice in each stage can be understood by considering the ratio of the decomposition powers, when the planting direction of the paddy rice is not only normal but also oblique to radar direction. We can also see that orientation angle compensation (OAC) is useful for improving the accuracy of the growth stage observation in late vegetative stage for oblique planting case.
