Remote Sensing lecture one

1. 1Remote sensing consists of the interpretation of measurements of [blank_start]electromagnetic energy reflected[blank_end] from or emitted a target from a vantage point that is distant from the target.

   1. Aelectromagnetic energy reflected
2. 2v = f[blank_start]requency x wavelength[blank_end]

   1. Arequency x wavelength
3. 3v = [blank_start]3x10^8 (The Speed of light)[blank_end]

   1. A3x10^8 (The Speed of light)
4. 4The Sun is [blank_start]a passive source of energy[blank_end]

   1. Aa passive source of energy
5. 5Active sources [blank_start]are lazers[blank_end]

   1. Aare lazers
6. 6Rayleigh Scattering is

   1. AParticles smaller than wavelength(Blue sky) is strongly wavelength dependent
   2. BParticles = wavelength(Water vapour) weak wavelength dependence
   3. CLarger particles, no wavelength dependence(Clouds)
7. 7Mie Scattering:

   1. AParticles smaller than wavelength(Blue sky) is strongly wavelength dependent
   2. BParticles = wavelength(Water vapour) weak wavelength dependence
   3. CLarger particles, no wavelength dependence(Clouds)
8. 8Non-selective scattering:

   1. ALarger particles, no wavelength dependence(Clouds)
   2. BParticles = wavelength(Water vapour) weak wavelength dependence
   3. CParticles smaller than wavelength(Blue sky) is strongly wavelength dependent
9. 9Absorption: [blank_start]Some wavelengths[blank_end] are absorbed by [blank_start]the atmosphere (CO2, Ozone etc.,)[blank_end] It affects where we look in the [blank_start]spectrum(Atmospheric window)[blank_end]

   1. ASome wavelengths
   2. Bthe atmosphere (CO2, Ozone etc.,)
   3. Cspectrum(Atmospheric window)
10. 10Passive sensors:

    1. AGeoEye
    2. BRadarSat
    3. CGLAs ICESat
    4. DETM Landsat
    5. EModis Terra and Aqua
    6. FInferferometric synthetic aperture radar

11. 11Active Sensors:

    1. ARadarSat
    2. BETM Landsat
    3. Cinterferometer Synthetic aperture radar
    4. DModis Terra and aqua
    5. EGeoEye
    6. FGLAS ICESat
12. 12SAR [blank_start](Synthetic aperture Radar)[blank_end] uses [blank_start]repeat images from a moving platform[blank_end] to build up [blank_start]high-resolution images[blank_end]. [blank_start]Aperture refers to antennae size[blank_end]

    1. A(Synthetic aperture Radar)
    2. Brepeat images from a moving platform
    3. Chigh-resolution images
    4. DAperture refers to antennae size
13. 13What is this?

    

    1. ACorner
14. 14Reflector Characteristics?

    

    1. AVolume Scattering
15. 15Reflector Characteristics

    

    1. ALambertian
