摘要: This article presents an analysis of the scattering measurements for entire wheat growth cycle by ground-based scatterometers at a frequency 5.3 GHz. Since ears are related to and yield, radar backscatter was analyzed two different periods, i.e., with without ears. Simultaneously, parameters such as soil characteristics well volume were periods during cycle. Wheat have been demonstrated great influence on backscatter; therefore, modified version water-cloud model used retrieving biomass should consider effect work retrieval models based adopts advanced integral equation simulate before heading stage from layer under after stage. The research results showed that retrieved synthetic aperture (ASAR) images agree data measured
