由于这种算法对信号及噪声的特性也未提出要求，因而也适合于超宽带雷达中的时延估计。

On the aspect of ultrasonic wave Transmit and Receive, we use two probes to realize the switching between transmitting and receiving mode; we also adopted a transmitted scheme based on intermissive multi-pulse, which develops the Time Difference with Interpolation, uses digital filter to adjust the waveform, and calculates the Time Delay with Correlation Arithmetic.
