其基本原理是利用了距离，多普勒分辨力来分离散射点，以使视角平面内目标的边界尺寸可以测量。
The rationale of the measurement is to use range and doppler resolution so as to distinguish various reflecting points of a moving target.
The numerical results show that the effect of quarter spherical defect to stress intensity factor in the finite body is the same as that in the infinite body.
