3. Cultivate compound applied talents with strong engineering practice ability and certain scientific research ability, and compound engineering and technical talents with innovative ability.

Definition of remote sensing technology:

1. Remote sensing technology is a technology to detect and identify targets by sensing electromagnetic waves, visible light and infrared rays reflected or radiated by targets at a long distance. For example, aerial photography is a remote sensing technology. The success of artificial earth satellite promotes the development of remote sensing technology.

2. Modern remote sensing technology mainly includes information acquisition, transmission, storage and processing. The complete system that completes the above functions is called remote sensing system, and its core component is the remote sensor that obtains information. There are many kinds of remote sensors, mainly cameras, TV cameras, multispectral scanners, imaging spectrometers, microwave radiometers, synthetic aperture radars, etc.

3. Transmission equipment is used to transmit remote sensing information from remote platforms (such as satellites) back to the ground station. The information processing equipment includes a color synthesizer, an image reader and a digital image processor.
