几个关于阵列天线的仿真程序，运行环境为matlab,需要用到阵列信号处理工具箱，运行极了一看见结果。(Several on the antenna array simulation program, operating environment for matlab, need to resort to array signal processing toolbox, running great to see the results of one.)

当信号采样点数很少时，不能很好的恢复原模拟信号，导致原始信号中的一部分丢失。而当信号的采样点数增多到1024时，其分辨率很好，可以有效的区分信号的信息，当采样点数继续增多时，其恢复为原始模拟信号的精度越高且不丢失原始信号。(When the signal is small when the sampling points can not be good to restore the original analog signal, causing part of the original signal is lost. When the signal is increased to 1024 sampling points, its resolution is very good, can effectively distinguish the signal information, continue to increase when the sampling points, its back to the higher accuracy of the original analog signal without loss of the original signal.)

Mammography is one of the available techniques for the early detection of masses or abnormalities which is related to breast cancer. Breast Cancer is the uncontrolled of cells in the breast region, which may affect the other parts of the body. The most common abnormalities that might indicate breast cancer are masses and calcifications. Masses appear in a mammogram as fine, granular clusters and also masses will not have sharp boundaries, so often difficult to identify in a raw mammogram. Digital Mammography is one of the best available technologies currently being used for the early detection of breast cancer. Computer Aided Detection System has to be developed for the detection of masses and calcifications in Digital Mammogram, which acts as a secondary tool for the radiologists for diagnosing the breast cancer. In this paper, we have proposed a secondary tool for the radiologists that help them in the segmentation and feature extraction process.
