ultrasonic sensor signal

By programming the FPGA, we finished the hardware control cooperating with the DSP, the OSD function, the collection and dealing with the ultrasonic sensor signal.

主要对FPGA进行编程设计，配合DSP完成了系统硬件控制、OSD以及超声波雷达信号的采集、处理等功能。

Compared with correlation measure by adopting ultrasonic and capacity as sensor, it has lower cost that adopting random signal of fluctuating pressure by pressductor measured.

与采用超声波、电容作为传感器的相关测量法相比，利用压力传感器测量压力脉动随机信号的相关测量法成本较低。

The digital filter was done to the output signal of the analog ultrasonic sensor.

对模拟量超声波传感器的输出信号进行了数字滤波。
