Dual Radar SAR Controller
Josiah Smith
The following is a user guide for the Dual Radar SAR Controller graphical
user interface (GUI) to operate the dual radar synthetic aperture radar (SAR)
scanner. The scanner was designed in the Spring semester of 2022 by Josiah
Smith (RA), Yusef Alimam (UG), and Geetika Vedula (UG) with multiple axes of
motion for the radar and target under test. The system is operated by a
personal computer (PC) running MATLAB. An AMC4030 motion controller is employed
to control the mechanical system. An ESP32 microcontroller synchronizes the
mechanical motion and radar frame firing to achieving precise positioning at
high movement speeds; the software was designed by Josiah Smith (RA) and
Benjamin Roy (UG). A second system is designed that employs 3-axes of motion
(X-Y + rotation) for fine control over the location of the target under test.
The entire system is capable of efficiently collecting data from colocated and
non-colocated radars for multiband fusion imaging in addition to simple single
radar imaging.
