超级地震检波器测试仪是一种实现精密测量的工具 ,它应该具有抗噪声能力。在精密测量中 ,要取得准确可靠的结果 ,除了测试仪器本身必须具有足够的精度和可靠性之外 ,试验设计、数据处理和结果分析等问题也不可忽视。文章指出了开发超级地震检波器测试仪的出路是在适当提高A/D转换精度的基础上 ,加强抗噪性能 ,即对测试信号采用有效滤波或其它信噪分离技术。采用对加高斯白噪声的地震检波器响应信号进行 1 6位A/D量化采样 ,利用Marquardt算法识别其两个基本参数———自然频率和阻尼。此方法用于超级地震检波器测试仪 ,有助于提高测试精度
The Super Seismometer Tester is a tool for precision measurement that should have noise immunity. In precision measurement, in order to obtain accurate and reliable results, in addition to the test instrument itself must have sufficient accuracy and reliability, the experimental design, data processing and analysis of the results can not be ignored. The article points out that the way to develop a super geophone tester is to improve the anti-noise performance on the basis of properly improving the A / D conversion accuracy, that is, applying effective filtering or other signal-noise separation techniques to the test signal. A 16-bit A / D quantized sample of the geophone response signal with Gaussian white noise was used to identify two of its basic parameters, natural frequency and damping, using the Marquardt algorithm. This method is used in the Super Geophone Tester to help improve test accuracy
