Firstly, with the consideration of the frequency and aspect Angle dependent parameters of the low frequency UWB-SAR, the radar equation for calibration is proposed.

首先充分考虑了系统参量的频率和方位角特性，提出了适合低频uwb - SAR校准的雷达方程。

The principle of measurement and mathematical model of the solar aspect angle were given and a scheme of practicable digital telemetering system for the measurement was also propounded.

文中给出了太阳方位角测量原理及太阳方位角传感器数学模型，提出并实现了数字太阳方位角遥测系统。

The first aspect is from the angle of the relationship of urban economy and real estate industry, and the method correlation degree analysis and industrial line analysis are used to discuss.

第一方面从房地产业与城市经济关系的角度来论述，并运用了关联度分析和产业链分析来加以论证；
