		<abstract>Os modelos de transferência radiativa, aplicados ao estudo do comportamento espectral de dosséis agrícolas, constituem em uma poderosa ferramenta auxiliar para a utilização das técnicas de Sensoriamento Remoto na agricultura. Neste trabalho, foi avaliado o desempenho dos modelos SUITS e SAIL, através da comparação do Fator de Reflectância Bidirecional (FRB)calculado pelos modelos, com aquele medido em experimento de campo sobre a cultura de soja (Glycine max (L.) Merrill). De acordo com os resultados desta pesquisa, chegou-se às seguintes conclusões: a) Os dois modelos tiveram tendências de comportamento semelhantes, porém o SAIL foi superior ao SUITS, principalmente na faixa do vermelho e do infravermelho próximo; b) Para o modelo SAIL, a regressão linear simples entre o FRB medido e o calculado forneceu valores de r2 de 0,77 para comprimentos de onda no centro da faixa de 740 nm a 861 nm; c) Os modelos estudados não dependem da densidade do dossel na vertical; d) Através de uma análise de sensibilidade verificou-se que dos dados de entrada para o modelo SAIL, a distribuição angular de folhas e as propriedades espectrais destas necessitam de uma boa precisão, para que os resultados sejam satisfatórios. ABSTRACT: The radiative transfer model applied to the spectral behavior of the agricultural crop canopy studies, consist of an aid-efficient instrument to carry out the use of remote sensing techniques for agriculture. In this work SUITS and SAIL canopy reflectance models performance was evaluated, based on the comparison between calculated and measured Bidirectional Reflectance Factor (FRB) in a soybean (Glycine max (L.) Merrill) under the same conditions. According to this research, it was concluded that: a) SUITS and SAIL models had similar tendencies, but SAIL model performance was better than SUITS model; b) for the SAIL model, the linear regression between calculated and measured FRB had a r2 value of 0,77 for the wavelength in the red spectral region, and r2 value of 0,74 from 740 nm to 861 nm spectral range; c) both models do not depend on the canopy vertical density; d) through sensitivity analysis, it was found that a good precision in the input data for SAIL model, namely angular distribution and spectral attributes of leaves, is needed to obtain a good performance in the FRB simulation.</abstract>
