SkyRadar's SAR system builds on the FMCW base module. Set on a linear high-precision conveyor, driven by a servo motor and controlled with an industrial drive system, it produces a variable number of radar images which are aggregated in a time-multiplex approach.
Synthetic Aperture Radar (SAR) hardware setup, with servo controlled movement of the antenna on a linear rail.
A high precision brushless DC servo motor with integrated controller (stepper) actuates the linear drive.

The linear conveyor creates the defined and highly precise displacement, allowing the radar to shoot shifted images that will be aggregated into one high resolution images in a subsequent time-multiplex principle.
