代码说明：

说明：  空气耦合超声传感器的接收信号掺杂有大量噪声信号，根据传感器的参数设计匹配带通滤波器，提高接收信号的质量。(The received signal of air coupled ultrasonic sensor is adulterated with a large number of noise signals. According to the parameters of the sensor, a matched band-pass filter is designed to improve the quality of the received signal.)
