验证可用，包括广义互相关函数GCC时延估计，进行波形数据分析,可以得到很精确的幅值、频率、相位估计，多抽样率信号处理，采用的是脉冲对消法。- Verification is available, Including the generalized cross-correlation function GCC time delay estimation, Waveform data analysis, You can get a very accurate amplitude, frequency, phase estimation, Multirate signal processing, It uses a pulse of consumer law.
