The dither signal removal is one of the important works of mechanical dithered ring laser gyro signal processing.To meet the requirements of the fast tracking community,the hardware and software design of the adaptive dither stripper has been carried out based on FPGA.Then,the dither stripping effect and gyro’s null drift stability tests have been performed under the static condition. Finally, the dynamic response property of dither stripper has been tested,and the dynamic response curves are presented.The zero latency feature of LMS adaptive dither stripper has been verified.The results showed that most of the dither signal has been removed by the dither stripper with almost no phase latency,and the dither stripper can be used for real time angular rate measurement.
