ABSTRACT

This bibliography is an outgrowth of a conference held at the

University of California at Los Angeles in June I960 to discuss the

aspects of long-range high-frequency radio propagation that affect

radio location and direction finding, and the related problems of

measurement and analysis. A group of the papers presented at the

conference was published in the Radio Propagation Section (Section D)

of the Journal of Research of the National Bureau of Standards, May - June issue, 1961. In connection with the conference the Numerical

Analysis Research Staff of UCLA prepared a bibliography of published

work on the conference subject covering the period 1935-1959. For

this Technical Note the UCLA bibliography has been edited and extended

to include some papers published in I960 and the first half of 1961.

This compilation, though by no means exhaustive, includes over 850

titles on direction finding and related topics ranging from instrumental

details through observations and data analysis to theories of propagation.

Bibliography on Direction Finding and Related Ionospheric

Propagation Topics (1955-1961)

Introduction

In June I960 a conference on transmission problems related to

high-frequency direction finding was held at the University of

California at Los Angeles under its sponsorship and in cooperation

with the Office of Naval Research. The purpose of the conference

was to discuss the aspects of long-range high-frequency radio

propagation that affect radio location and direction finding, and the

related problems of measurement and analysis. A group of the papers

presented at the conference was published in Radio Propagation,

Section D of the Journal of Research of the National Bureau of

Standards (Volume 65D, Number 3, May-June 1961).

In connection with the conference the Numerical Analysis

Research Staff of the University of California at Los Angeles prepared

a bibliography of published work on direction finding and related topics

for the period 1955-1959, which formed the basis for this Technical

Note. For the present work the UCLA bibliography was edited and

extended to include some of the papers published in I960 and the first

half of 1961 as well as some earlier ones which came to the editor' s

attention.

The selection of titles to be included in this bibliography was

based on a rather broad interpretation of direction finding and related

topics. The topics range from instriimental details through observations

and data analysis to theories of propagation. Such breadth of coverage

militates against exhaustiveness especially in fields not closely related

1
-2-

to direction finding in the narrow sense of the term. Nevertheless it

is hoped that a representative sample of papers from these fields has

been included; at least enough to suggest some new approaches or

solutions to some users of the bibliography. The editor would

appreciate comments on the work, particularly in regard to serious

omissions, new developments, or errors of citation. These will be

collected for use if future supplements or revisions are decided upon;

the commxonications would probably influence the decision.

The bibliography was brought up to date principally by searching

all issues of Electrical Engineering Abstracts from January I960

through July 1961 under the relevant subjects. In addition, certain

recent bibliographies and the reference files of some NBS personnel

were searched for pertinent titles. The bibliographies on radio wave

propagation edited by Wilhelm Nupen and listed under his name were

particularly useful. Another important source was the Backscatter

Literature Survey prepared by Hagn, Nielson, and Smith. Their

contributions and those of the NBS personnel whose files were opened

to the editor are gratefully acknowledged.

References to individual articles have been confined to the period

1955 through about mid-1961, iinless the article was a review of the

field. General works such as bibliographies, proceedings of conferences, surveys, and textbooks were included as far back as about 1940

in order to provide access to the earlier literature. Such general

works were accepted with an even broader interpretation than the

individual articles; some indication of their usefulness is given by

mentioning the number of references, the inclusion of abstracts and

so forth.
-3-

During World War II both sides did extensive work on radio

direction finding, the results of which were largely classified. Since

then much of the literature and many of the original laboratory reports

have been declassified. Some bibliographies and surveys of this

literature are listed herein under the name of the country in which the

research was carried out. A more complete bibliography and a discussion of some of the wartime work is given in a paper by K. A.

Norton entitled "Radio Wave Propagation During World War II" published in Proc. IRE for May 1962. The editor is grateful to

Mr. Norton for providing a copy of this paper prior to its publication.

Since the principal emphasis was to be on long-distance propagation, only a few papers on tropospheric propagation have been

retained. These include some papers indicating the magnitude of

tropospheric refraction and some whose theory or techniques could be

applied to long distance direction finding. A recent tropospheric

bibliography is listed under R. L. Abbott.

"A Survey and Bibliography of Recent Research in the Propagation

of VLF Radio Waves" by James R. Wait was published as NBS Technical Note No. 84 in May I960. Therefore the present listing includes

only references to later published works not included in his bibliography.

The titles are arranged alphabetically by the first author' s name

and when there is more than one author by the names of the co-authors.

When there is more than one paper by the same author, or authors,

the arrangement is chronological. Occasional titles are listed under

the institution or organization issuing them. Similar articles by the

same author but published in different journals have sometimes been

included for the convenience of users having access to only one of the

journals.
-4-

The abbreviations of the names of periodicals are mostly those

used by Chemical Abstracts. The titles of articles in foreign journals

are given in English followed by the original journal citation in

transliteration and an indication of whether the journal or article has

been translated (when such information was available). No attempt

has been made to give the complete citation of the article in the

translated journal since this usually agrees with the original except

for pagination. Whenever possible the citation includes volume number,

issue number, month and year to assist the user in locating references

even when there is a typographical error in one of these.

Since there are over 850 titles in the bibliography, a group of

code letters was devised to classify the articles according to broad

subject and type. Opposite each author' s name there is a key consisting

of a year and from one to three letters indicating the most important

categories into which the paper can be classified. In most cases the

year of publication is given in the key. However, for conference

proceedings the year of the conference is usually given in the key and

the year of publication in the citation. For translated textbooks the

key shows the year of publication in the original language and the

citation the year of publication in English.

A list of the categories and some of the topics placed in each is

given below. It should be noted that the selection of categories was

most frequently based on the title and abstract of the paper and often

on the title alone. Despite these shortcomings, it is hoped that by

merely scanning the keys the user will be able to find the types of

articles in which he is interested.

I would like to thank Mrs. Dorene Briels for her help in

preparing the card file of references used to bring this bibliography

up to date. I am especially grateful to Mrs. Marion Andrews for

checking many of the citations, merging the card file and the original

list while typing the manuscript, and patiently making corrections on

the copy.
