In this paper the imaging of density and bulk compliance by diffraction tomography is being studied on the basis of velocity imaging. By inversion with such different angles, a series of inversion synthetic seismograms will be derived. To fit these seismograms, we can efficiently image density and bulk compliance (or velocity). Compared with pure velocity imaging, this algorithm is more complicated. First, more data of different directions are required; second, we can't make full use of those dafa. Even though...

In this paper the imaging of density and bulk compliance by diffraction tomography is being studied on the basis of velocity imaging.

Compared with pure velocity imaging, this algorithm is more complicated. First, more data of different directions are required; second, we can't make full use of those dafa. Even though a satisfied imaging result has been finally obtained through the computation of the data of tens of shots and receivers'. We inverted a model with several scatterers which formed a letter "A" and the density and the bulk com-phance have been reconstructed simultaneously. The distinct imaging results' show that this algorithm is feasible and can be applied to the imaging of complex structure.

本文在速度成像的基础上研究了同时对密度和压缩系数成像的散射波层析成像法.对不同散射角度的计算可以得到一系列反演图像,拟合这些图像,从而可以有效地达到对密度和压缩系数(或速度)成像的目的.与单纯的速度成像相比,增加了反演的难度.首先是对资料的方位性要求增加;其次是对资料的利用率下降.即便如此,从对较少量的炮点和检波点资料的数值计算来看,仍取得了满意的成像结果.我们对组成字母“A”的散射体结构进行了成像计算,结果能够同时再现密度和压缩系数,成像清晰,表明了方法的可行性,并能应用于复杂结构的成像问题.

The range resolution and the cross-range resolution of range-Doppler imaging radars are related to the effective bandwidth of transmitted signal and the angle through which the object rotates the relatively to the radar line of sight (RLOS) during the coherent processing time,respectively. In this paper,the superresolution imaging method of the linear prediction data extrapolation and discrete Fourier transform (LPDEDFT) is investigated for the purpose of surpassing the limitation imposed by the conventional FFT range-Doppler processing and improving the resolution capability of range-Doppler imaging radar. The LPDEDFT supererresolution imaging method,which is conceptually and computationally simple,consists of extrapolating observed data beyond the observation window by means of linear prediction,and then performing the conventional IDFT of the extrapolated data. The live data of a metalized scale model B-52 aircraft mounted on a rotating platform in a microwave anechoic chamber and a flying Boeing-727 aircraft are processed. It is concluded that,compared to the conventional Fourier method,either higher resolution for the same effective bandwidth of transmitted signals and total rotation angle of the object or equal-quality images from smaller bandwidth and total angle may be obtained by LPDEDFT.

距离—多普勒成像雷达的距离分辨力和横分辨力分别取决于发射信号的有效带宽和目标相对于雷达视线(RLOS)在相于处理区间内的转角。本文研究线性预测数据外推离散傅里叶变换(LPDEDFT)超分辨成像方法,旨在突破普通的FFT距离多普勒处理的限制,提高距离—多普勒成像雷达的分辨力。LPDEDFT在概念上和计算上都比较简单,分两步进行,先用线性预测方法把观测数据外推到观测窗之外,然后对外推过的数据进行普通的离散傅里叶变换。文中给出了B—52飞机缩比金属模型微波暗室转台实测数据和飞行中的Boeing-727飞机外场实测数据的成像结果。LPDEDFT与普通的傅里叶方法相比,在相同信号带宽和目标总转角的条件下可以得到更高的图像分辨力,或者可以用较小的信号带宽和目标总转角获得相同质量的图像。
