Scattering Characteristics of Targets above a Rough Surface in SAR Images

Figure 6

The 2D HH-polarization SAR images of the tank target above Gaussian rough surfaces with different sizes, in which the incident angle is (𝜃=75^∘, 𝜙=[30^∘,45^∘,60^∘]), the resolution is 0.25 m, and the maximum reflection number is 2. The gun barrel direction is set as 𝜙=0^∘. (a) The SAR image of the tank above the smaller rough surface at azimuth of 30^∘. (b) The SAR image of the tank above the larger rough surface at azimuth of 30^∘. (c) The SAR image of the tank above the smaller rough surface at azimuth of 45^∘. (d) The SAR image of the tank above the larger rough surface at azimuth of 45^∘. (e) The SAR image of the tank above the smaller rough surface at azimuth of 60^∘. (f) The SAR image of the tank above the larger rough surface at azimuth of 60^∘.
