函数信号发生器根据用途不同，有产生三种或多种波形的函数发生器，其电路中使用的器件可以是分离器件，也可以是集成器件，产生方波、正弦波、三角波的方案有多种，如先产生正弦波，根据周期性的非正弦波与正弦波所呈的某种确定的函数关系，再通过整形电路将正弦波转化为方波，经过积分电路后将其变为三角波。-Function Generator according to different purposes, there have three or more of the waveform function generator, a device used in the circuit can be separate devices, can also be integrated device, resulting in square wave, sine wave, triangle wave of the program how species, such as created in the first sine wave, according to the periodic non-sine wave and sine wave which was a function of a certain set, and then by the sine-wave shaping circuit into a square wave, after integrating circuit will turn it into a triangle wave.

：提出针对单极化合成孔径雷达(SAR)图像相干斑滤波算法性能的分层检验模型和综合评价 方法。模型分相干斑抑制程度和目标微波后向散射系数保持程度两个层次，包含的指标有等效视数、信号 杂渡比、回波辐射度损失、均值偏差、空间分辨率损失和峰值旁瓣比偏差六项-: Unipolar against synthetic aperture radar (SAR) image speckle filtering algorithm hierarchical test model performance and integrated evaluation. Model sub-speckle suppression and objectives of the degree of microwave backscattering coefficient to maintain the level of two levels, including the indicators have the equivalent depending on the number of signals crossing miscellaneous ratio, radiometric echo loss, the mean deviation, loss of spatial resolution and peak sidelobe than the deviation of the six
