  • The simulation of brightness temperature image is a necessary work in the passive microwave remote sensing. This paper introduces the brightness temperature tracing method for 3-D scene microwave radiometric image simulation, and describes the general requirements and considerations such as sky radiation, antenna smoothing and polarization rotation caused by multiple-reflection. Then a simulation model is established which can create more realistic imagery and reproduce the radiation phenomenology. Using this model the microwave radiometric phenomenology which is greatly deferent from optical and infrared ones is analyzed. Finally, the Lab building and airstrip are simulated in order to validate this model. The comparisons with field measurements indicate that this model is completely feasible in practice.
