New product: SPHYDER

SPHYDER (Smart Processing HYperspectral DEtection and Reconaissance)

was designed to respond to specific applications and to be installed on various

platforms.

During the development and after discussions with potential end-users it

appeared the need of obtaining Real-Time information during the mission.

The main requirements to be fulfilled for SPHYDER design and development:

• Compact and lightweight

• Custom

• Real Time Processing

The classes are related to the

different behaviours of the

Through the elaboration of

the spectrum associated to

the class, information can be

extracted on the deepness

and the type of lake-bed.
