The current spaceborne synthetic aperture radar systems are operated to illuminate the scene along the satellite flying direction. However, in many cases, the interested areas are not parallel to the flying direction, so an innovative smart imaging mode is acquired, which can be employed for illuminating scene along a given direction. A novel three-axis attitude steering method is proposed for smart...
The synthetic aperture ladar (SAL) is similar to the synthetic aperture radar (SAR) while working at optical frequency, which could provide higher resolution than SAR. However, due to the shorter wavelength, the vibration of the platform and atmosphere turbulence will induce more serious phase error, which results in the defocused SAL image with lower signal-to-noise ratio. A novel approximated observation...
