Effect of Motion Errors
The figure below shows a SAS image of a simulated point scatterer. The effects of sway and surge errors of various magnitueds are shown on this page.
The effect of a one-wavelength surge error is as shown:
Effect of a ten-wavelength surge error:
Effect of a one-wavelength sway error:
Image Flexibility With Known Motion
Providing the motion is known, the BDSP SAS imaging can form the image. In the case shown below, the platform motion is randomly generated as shown in the right of the figure. Each small line represents an array position. The top image shows the image formed with the known motion data provided to the imaging algorithm, while the lower image shows the effect of assuming a linear platform path.
