Description: xwch_test.m是主测试文件；biaoji.mat存放滤波器系数；xiangweicha.m用FFT计算相位差。
仿真框架为：
1.标记信号和双音信号续接作为发送信号；
2.对双音中一个频率分量的相位做偏移，再经过一个低通滤波器（引入线性相位，模拟收发不能同步测量现象）后，作为收到的信号；
3.用一个检测信号对收发信号进行相关运算；
4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点，从而推算出收发双音信号0相位点；
5. 输入0相位点位置，计算相对相位差。-xwch_test.m is the main test file biaoji.mat store filter coefficients xiangweicha.m calculated using FFT phase difference. Simulation framework: 1. Mark signals and then as a two-tone signal continued to send signals 2. On a two-tone frequency components of the phase shift to do, and then through a low pass filter (the introduction of linear phase, simulation can not simultaneously send and receive measuring the phenomenon), the as received signal 3. using a detection signal of the transceiver signal correlation operation 4. draw send and receive signals and related processed signal. Correlated signal of the cusp, which calculate the two-tone signal transceiver 0 phase point 5. Enter 0 phase point position, calculate the relative phase difference.

Description: 目前安防监控系统监控效率低、盲目性大的问题，设计了一种基于相位差（differenceofphase，DOP）的声源定位系统，介绍了系统的组成原理、软硬件电路设计与实现，提出了一种基于DOP的定位算法。该系统以DSP芯片TMS320F28335为核心，以麦克风为声音传感器，以云台为控制对象，实现了一种高效、低成本的嵌入式声源定位系统。实验结果表明，该系统反应快、定位准、可靠性高。-Aiming at making up for the deficiency and blindness of the present monitoring system, this paper creatively pro- posed a novel position scheme based on phase difference to improve sound source localization system and gave a detailed descrip- tion for its composition principle and circuit design as well as implementation. The location system centered with DSP chip TMS320F28335 of TI corporation utilized microphone as sound sensor and PTZ as controlled member to achieve an efficient and low cost embedded sound source location system. Massive experiment statistics confirmed that the system has a prominent im- provement in reaction velocity, position accuracy and reliability.
