| Abstract: | Soil moisture detection is very important for high precision soil moisture retrieval by using airborne active and passive microwave sounder. According to the requirements of detection mission and the complicated vibration and thermal conditions of airborne experiment, the structure of the sounder is designed, and the mechanics analysis and thermal design for the system structure is carried out. The result shows that the structure design of the microwave sounder is reasonable. Then, an airborne detection-flight test is carried out. The result shows that the system structure fully satisfies the requirements of the flight environment and the sounder works normally. The structure of the microwave sounder has the advantages of compact layout, high precision, stable operation and easy assembly. It can provide reference for the structure design of similar airborne payload. |
