Design and Implementation of Servo System Controller for Maritime Frequency Modulated Continuous Wave Radar

In recent years, Frequency Modulated Continuous Wave (FMCW) radar has been widely used due to its simple structure, small size and high detection performance, and has achieved rapid development. The servo system is an important part in FMCW, used to drive the stepping motor and drive the antenna rotation, to achieve the movement of the antenna control, its performance directly affects the dynamic performance and measurement accuracy of FMCW radar. This paper introduces the composition and principle of the radar servo system, analyzes its performance requirements, designs a radar servo system controller, details its hardware composition, function and configuration, software function, module and process; Finally, the system test is carried out, and it has been successfully applied to an X-band FMCW radar. The practical application effect is good, and it has important application value.
