基于DSP的声纳电功率测量系统

正交双通道处理技术保留了信号的幅度和相位信息,用这种方法可以实现无理论误差地测量音频正弦信号有效功率。为了实现对声纳发射有效电功率的测量,基于此技术设计了声纳发射有效电功率测量系统,系统采用专用数字信号处理器DSP和单片机AT89C51构成双微处理器工作方式,数字信号处理器用来实现各种算法和完成数据运算,单片机AT89C51用来实现系统控制。通过实际测量,此系统满足设计要求并在实际中得到应用。

Measurement system of sonar electric power with DSP

The processing technique based on double channels of perpendicular retains information of the range and phase of signal. The no theory error measurement of audio sine signal active power with this method is achieved. Based on this technique, the measurement system of sonar transmitted active electric power is designed. The system is based on double microprocessors of digital signal processor and single chip AT89C51.arithmetics and operation of datum are achieved by DSP, the system control is achieved by single chip AT89C51. This system meets need of design by practice measurement and is applied to practice.
