| 1 | Now a method is suggested which uses a passive remote sensing equipment-microwave radiometer for detection and identification of air object. | |
| 2 | MODIS and Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) supplies different methods of snow detection. | |
| 3 | The image was made with data from the Advanced Very High Resolution Radiometer on the NOAA-18 POES satellite. | |
| 4 | The result helps to enhance the target identification ratio of the MMW radiometer. | |
| 5 | Observation of surface sunny ultraviolet radiation is mainly done by the UV spectroradiometer and filter ultra violet radiation meter. |
