The present author suggests a new distribution function for the roots of the complex polynomial corresponding to the nulls of the radiation pattern of a linear antenna array on the unit circle in a complex plane which is more general than the one suggested by the same author in a previous paper[2]. The new distribution function is of the form

在本文中,作者提出了与线形天线阵辐射图形中零点相对应的复量多项式的根在复数面中单位圆上的一个分布函数,它比作者在前一篇论文中所提出的分布函数有更普遍的意义。这个普遍函数是: 当ψ_0和ξ被适当地选择时,这个普遍函数所代表的天线阵将包括以下各式天线阵作为特例:(1)均匀横射式天线阵;(2)均匀端射式天线阵;(3)谢昆诺夫天线阵;(4)道尔夫-捷比谢夫天线阵当阵中单元数不超过7时。但是,应用所提出的分布函数并当合理地选择ψ_0和ξ时,却可以改善以上各式天线阵,尤其在压小主瓣附近的旁瓣方面。这一情况是具有重大实用意义的。此外,因为天线阵中各单元的场强或其方向图中的旁瓣一般都随着离开主瓣的角距的增加而下降的,所以为了使天线阵的总方向图有均等或接近均等的小的旁瓣(这是具有实用意义的),就必须设计一个由均匀辐射器所组成的天线阵,它有随着离开主瓣的角距的增加而上升的小的旁瓣。利用谢昆诺夫的分布或道尔夫-捷比谢夫的分布都不能达到此目的,但是应用所提出的分布函数却可以办到。计算结果证实了上述各点。 在本文中,作者还将代表各式天线阵的多项式的乘积形式加以展开,从而将其中的系数化为显式以便于阵中各单元上相对电流的计算。

The paper includes two parts. The first part is a theoretical part, in which the characteristics of holography as applied to detection is discussed, and the notion of "detecting holography" is proposed. The principal difficulty encountered in applying elastic or electromagnetic waves to the earth media is the poor longitudinal resolution of monochromatic holography. Prom the viewpoint of the communication theory and the antenna array theory, the monochromatic holography is examined, and its relations to correlation detection, matched filters as well as phased array anteenas are illustrated. Multifrequency synthetic detective holography is developed as a possible approach to the solution of longitudinal resolution problem. Its principles are discussed, its relations to the "impulse holography" and the formulas for the longitudinal resolution are deduced. Finally, examples of two-dimensional computer simulation are presented to illustrate the feasibility of the method.The second part is an account of experiments made in water-tank for the microwave multifrequency synthetic detecting holography. The results of computer reconstruction using interference-type holograms give evidence to prove the high resolution and good imaging quality of the method.

本文分两个部分。第一部分从理论上探讨了全息成象应用于探测时的特点,提出了“全息探测成象”的概念。指出对地层介质使用弹性波或电磁波时,关键问题是纵向分辨力低。作者从信息论和天线阵理论的观点探讨了单频全息成象,研究全息成象和相关检测、匹配滤波以及相控阵之间的联系,提出了多频合成全息探测成象作为解决纵向分辨力的一个方法。探讨了它的原理,指出了它和“脉冲全息成象”的关系,导出了纵向分辨力公式,并给出了二维理论模型计算的结果,以说明方法的可行性和应用前景。 第二部分为实验部分,叙述了多频合成微波全息探测成象的试验。采用二维干涉型全息图做了简单模型的水槽试验,由计算机成象的结果证实了多频合成法的高分辨力和良好的成象质量。

After a brief description on the prineiples of holography and a discussion on the physical fundamentals relating to the application of holography to borehole electromagnetic wave exploration, the conleept of multiple-hologram and the associated teelmique for its synthetic imaging are presented. It is demonstrated that for bore-hole electromagnetic wave exploration the (curves from various fixed-point and synchronously moving measurements can be processed jointly, using the multiple-hologram synthetic imaging technique, to improve the resolution and image quality. It is also proved that this process of synthetic imaging of the multiple-hologram is equivalent in principle to the imaging process of dual-focussed scanning, in which, both the receiving and the tramsmitting antenna arrays are foeussed sequentially on each imaging point. The two-hole penetration method and the single-hole reflection method have been discussed and the relevant formulas for calculation given. Problems encountered in data processing, such as the interferences caused by source point images as well as their elimination, t'he problem of screened regions in penetra-tion holography and the problem of double images occurring in samelevel synchronously moving measurements, in which the transmitting and the receiving points are at the same level, are diseussed, supported by the results of computer simulations using the diffraction point model. Finally some results of data processing for water tank experiments and a few tentative calcelations of field data are shown.

在简述了全息成象的一般原理,并讨论了全息成象应用于钻孔电波勘探的物理基础之后,着重介绍了多重全息图的概念及其合成成象技术.指明了对钻孔电波勘探的多次定点观测曲线和多次同步观测曲线,可利用多重全息图及合成成象技术进行联合处理,以提高分辨力和成象质量.并证明这相当于接收天线阵和发射天线阵依次聚焦在每一成象点上的双聚焦扫描成象的过程.文中对双孔透射法和单孔反射法都进行了讨论,并给出了相应的计算公式;然后讨论了资料处理中的几个问题,如发射点象的干扰及其消除、透射全息的屏蔽区问题、水平同步成象时的双象问题等,并同时介绍了用衍射点模型进行计算机模拟的结果。最后给出了对水槽模型试验资料的处理结果和野外资料的试算结果.
