RADIO DIRECTION FINDING AND THE RESOLUTION OF MULTICOMPONENT WAVE-FIELDS
New techniques of radio direction-finding have been developed in recent years, based on various types of wide-aperture antenna arrays, multichannel receiving systems and digital signal-processing methods. Modern direction finders, capable of measuring elevation angles as well as azimuth angles, have become powerful tools for research into ionospheric physics and h.f. radio propagation. These new applications and the steady improvement in instrumental accuracy have led to new requiremnts; in particular, the resolution and identification of closely-spaced rays arriving at the receiving site assume greater importance. Various attacks on the problem of ray resolution are described in this volume, with emphasis of the methods of wavefront analysis developed by Dr. Gething and his co-workers; the collection and interpretation of ionospheric data for the purpose of mode identification are also discussed. Research workers in radar, sonar and radioastronomy as well as h.f. -direction-finding will find the book of great interest.
