Table 7-1 Hardware
Tool Details
C-Beam® Linear Actuator 1000mm with NEMA 23 Motor
IWR6843AOPEVM or IWR6843ISK Both evaluation modules (EVM) were used for testing
DM542T Digital Stepper Driver A stepper motor to allow accurate rotation speed for static residual movement
Microcontroller Used to set speed of NEMA 23 Motor for static residual movement
Camera Tripod Used to mount EVM to required height
Corner Reflectors RCS of 0.14 m2 and 40 m2. Stainless steel was used, however aluminum works as well.
