本课题研制了一种宽频带的数字锁相放大器，可以完成自动增益和相位 可调整，最长积分时间为100s，适合于频率从10Hz到10kHz，幅值从100nV 到10mV的微弱正弦信号检测。测量结果表明，当采样点数N大于8192时， (This project developed a wideband digital lock-in amplifier, can be completed automatically adjustable gain and phase, the longest integration time of 100s, suitable for the frequency range from 10Hz to 10kHz, amplitude from 100nV to 10mV of weak sine signal detection. The measurement results show that, when the sampling point number N is greater than 8192 hours,)

测向定位 信号处理思想 ESPRIT的思想在于，将传感器阵列分解为两个完全相同的子阵列，两个子阵中每两个相对应的阵元具有相同的平移，即要求阵列具有平移不变性，每两个位移相同的阵元匹配成对。实际中许多阵列满足这个条件，比如等距直线阵。它还有一些改进演算法，如最小二乘ESPRIT (LS-ESPRIT)，整体最小二乘ESPRIT(TLS-ESPRIT)等(Finding ideological positioning signal processing ESPRIT thought that the sensor array is divided into two identical sub-arrays, two sub-arrays in each of the two corresponding array element has the same translation, which requires an array with a translation invariance, each two identical displacement picket matching pairs. Many of the actual array satisfy this condition, such as isometric linear array. It also has improved algorithms, such as least-squares ESPRIT (LS-ESPRIT), the overall least squares ESPRIT (TLS-ESPRIT), etc.)

首先对图像进行了边缘检测，设计相应的结构元素对图像进行腐蚀，再进行图像聚类和填充图像。(First, the image edge detection, the design of structural elements corresponding to the image etched image clustering and then fill the image.)
