  2. Spaceborne Imaging Radar - Wikipedia

    en.wikipedia.org/wiki/Spaceborne_Imaging_Radar

    Once from the Space Shuttle Endeavour in April 1994 on and again in October 1994 on . The radar was run by NASA's Space Radar Laboratory. SIR utilizes 3 radar frequencies: L band (24 cm wavelength), C band (6 cm) and X band (3 cm), [1] allowing for study of geology, hydrology, ecology and oceanography. Comparing radar images to data collected ...

    ASTER image draped over terrain model of Mount Etna. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a Japanese remote sensing instrument onboard the Terra satellite launched by NASA in 1999. It has been collecting data since February 2000. ASTER image of Rub' al Khali (Arabia's Empty Quarter)

  4. Point spread function - Wikipedia

    en.wikipedia.org/wiki/Point_spread_function

    The degree of spreading (blurring) in the image of a point object for an imaging system is a measure of the quality of the imaging system. In non-coherent imaging systems, such as fluorescent microscopes, telescopes or optical microscopes, the image formation process is linear in the image intensity and described by a linear system theory. This ...

    This radar image acquired by the SIR-C/X-SAR radar on board the Space Shuttle Endeavour shows the Teide volcano. The city of Santa Cruz de Tenerife is visible as the purple and white area on the lower right edge of the island. Lava flows at the summit crater appear in shades of green and brown, while vegetation zones appear as areas of purple ...

  8. Image formation - Wikipedia

    en.wikipedia.org/wiki/Image_formation

    If y is the max radial size of the image then θ is the field of view of the lens. While the image created by a lens is continuous, it can be modeled as a set of discrete field points, each representing a point on the object. The quality of the image is limited by the aberrations in the lens and the diffraction created by the finite aperture stop.

  9. Multispectral imaging - Wikipedia

    en.wikipedia.org/wiki/Multispectral_imaging

    Multispectral image of Bek crater and its ray system on the surface of Mercury, acquired by MESSENGER, combining images at wavelengths of 996, 748, 433 nm. The bright yellow patches in other parts of the image are hollows. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.
