This paper presents a novel and efficient real-time multi-target imaging technique.First,the motion parameters of each target is estimated by applying a new time-frequency technique(the modified short-time Fourier'transform)to the received echoes. Then ,motion compensation is performed to get the image of the targets.Although the image is poor,the contour of target is distinguishable one from another.So we can get the signal of individual target by windowing. After applying a new ISAR motion compensation technique which called scattering centroid tracking to the windowed signal,we finally obtain the high-quality image of every target. Compared with the parameterbased (such as MLE)compensation, the proposed technique requires much less computation and is easy for implementation. Computer simulations have shown the effectiveness of the technique.

Based on the BIE( boundary integral equations)introduced by the authors in Reference, a new method of 2-D resistivity tomography(RT) is constructed in this paper. It is different from the RT methods which is based on the finite element method and alpha centers method. This method is unnecessary to compute the Jacobian matrix and to do linear approximation. It can not only save computing time and make the iteration processes of inverse stable, but also do well for RT when the electrical contrast of subsurface is big, so it clearly improves the practicability of RT. The numerical modeling results given in this paper show that the method is effective.

本文基于作者在文献[1]中提出的边界积分方程,建立了一种新的二维电阻率层析成像方案。与目前国内外用有限元法和α中心法的成像方法相比,该方法无需计算雅可比矩阵,也不必做线性化近似。这不仅节省了计算时间,而且使成像迭代过程稳定,可以对实际上广泛存在的大电性对比度介质获得满意的成像效果,从而大大提高了电阻率层析成像技术的实用性。文中给出的数值模拟结果显示了该方法的有效性。
