Compute the grazing angle of a SAR image projected on the image display plane of an antenna phase center located at [1000,2000,5000] meters with respect to a scene centered at [10,10,10] meters. Assume the slope angle for the image display plane is .
Measured line of sight vector from the scene center to the antenna phase center, specified as a 3-by-N matrix in meters. Each column of pos represents a measured line-of-sight position. The geometric location of the antenna phase center at the center of the processing aperture is the aperture reference point. The antenna phase center serves as the reference point for the phase history of the received signal.
Example: [1000;2000;5000]
Data Types: double
Slope angle, specified as a scalar between 0 and 90°. The slope angle is the angle between the image display plane and the scene center plane.
Data Types: double
Antenna phase center traveling axis, specified as 'x', 'y', or 'z'.
'x' — The antenna phase center travels in the x-direction and the surface plane is the xy-plane.
'y' — The antenna phase center travels in the y-direction and the surface plane is the yz-plane.
'z' — The antenna phase center travels in the z-direction and the surface plane is the zx-plane.
Display grazing angle, returned as a 1-by-N row vector in
degrees. The display grazing angle is the angle between the vertical projections of the
slant range vector onto the image display plane and the scene center plane. The image
display plane is the plane onto which the image formation processor projects the
scatterers in a 3-D scene.
