Cao方法

传统的高分辨波达方向（DOA）估计算法中，一般都假设信号位于远场，此时入射到阵列的信源波前为平面波前，空间信号的定位参数可由DOA来确定。然而，当信源处于阵列的Fresnel区域时，信号波前需用球面波来描述，每个信源的定位信息要用DOA和距离联合描述。因此，远场情况下的一些线性理论推导已不再成立，传统的远场算法的估计不再适用(In traditional high resolution direction of arrival (DOA) estimation algorithms, it is generally assumed that the signal is located in the far field, where the source wavefront incident to the array is plane wavefront, and the location parameters of the spatial signal can be determined by DOA. However, when the source is in the Fresnel region of the array, the wavefront of the signal needs to be described by spherical wave, and the location information of each source needs to be described by DOA and distance. Therefore, some linear theoretical deductions are no longer valid in the far-field case, and the estimation of the traditional far-field algorithm is no longer applicable.)

有一个圆环，其中小院半径为2.5，大圆半径为7。编程定义一个circle类，含有私有变量半径r，能够初始化r，计算圆面积。主函数中通过定义2个对象（大圆和小圆）来计算出圆环的面积。(There is a circle, of which the radius is 2.5 and the radius is 7. Programming defines a circle class, which contains the private variable radius R. It can initialize R and calculate the circle area. In the main function, the area of the circle is calculated by defining 2 objects (large circles and small circles).)
