satellite remote sensing |
卫星遥感测量 |
Observation of the Earth’s surface and atmosphere by a satellite equipped with a sensor.
用装有传感器的卫星观测地球表面和大气。 |
||
2 |
active sensor |
主动式传感器 |
Instrument that itself emits the energy required to illuminate the target and receives the waves it reflects.
它本身发出照亮目标所需的能量并接收其反射的波的仪器。 |
||
3 |
data recording |
数据记录(技术,方法) |
If the satellite in unable to communicate with the terrestrial station, data is registered onboard and transmitted later.
如果卫星无法与地面站通信,数据将在船上登记并随后传输。 |
||
4 |
passive sensor |
被动[无源]传感器 |
Instrument that receives the waves produced when the target reflects the Sun’s natural rays.
接收目标反射太阳光时产生的波的仪器。 |
||
5 |
energy source |
能源 |
At the origin of the remote sensing process is an , for example the Sun, used to illuminate the target.
在遥感过程的起源是一个,例如太阳,用来照亮目标。 |
||
6 |
natural radiation |
天然辐射 |
When the sky is clear, the satellite captures the reflection of the Sun’s rays from the Earth’s surface.
当天空晴朗时,卫星捕捉到太阳光从地球表面的反射。 |
||
7 |
data processing |
【电脑】数据处理 |
Raw data is interpreted and analyzed to extract information about the target.
对原始数据进行解释和分析,以提取有关目标的信息。 |
||
8 |
data reception |
数据接收 |
Raw data reaches the terrestrial station in digital form.
原始数据以数字形式到达地面站。 |
||
9 |
reflection [rɪ’flekʃn] |
反射 |
Phenomenon by which natural or artificial waves bounce off the target and toward the satellite.
自然波或人造波从目标上反射到卫星上的现象。 |
||
10 |
artificial radiation |
人工辐射 |
When atmospheric conditions hide the Sun’s rays, the active sensor itself emits radiation waves.
当大气条件掩盖了太阳光线时,主动传感器本身就会发出辐射波。 |
||
11 |
data transmission |
资料传送,数据传送 |
The sensor transmits raw data, if possible immediately, to a terrestrial station for processing.
如果可能,传感器会立即将原始数据发送到地面站进行处理。 |
