A simple based on DSP antenna controller of weather radar

This paper describes a simple based on DSP antenna controller which integrates SDC (synchro to digital converter) and RDC (resolver to digital converter) with antenna control logic calibration of the antenna angular code and adjustment of the radar antenna control system. It makes the antenna control system hardware simple, compact, stable, low-cost, highly flexible and easily maintainable. It is affordable for a low-cost X-band weather radar of weather modification operation. The paper starts with a simple description of the hardware architecture and then analyzes the angular resolution and accuracy. Finally it presents auto-angle code calibration and adjustment of the radar antenna control system.
