Earth Observation Sensors
The sensors mounted on earth observation satellites for monitoring natural resources and the environment can be broadly classified as optical sensors or microwave driven radars. Their use will depend on the application, although as they both have their own particular characteristics, they compensate each other.
The majority of multi-spectrum type optical sensors, for example, are suitable for collecting large volumes of information and combining colors, while panchromatic sensors are effective in acquiring high-resolution pictures. Microwave driven, all-weather synthetic aperture radars are useful for day and night observations.
NEC has advanced technologies and abundant experience in both optical sensors and radars.
