Current direction-finding practice

Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1958
Direction-finding practice in Britain is reviewed over the frequency band 10kc/s–400Mc/s; the survey is restricted to land-based systems. Current applications are outlined, the factors affecting accuracy are discussed with particular reference to those concerned with propagation, and equipment is described.The applications are numerous, ranging from ...

Finding Dominators in Directed Graphs

SIAM Journal on Computing, 1974
This paper describes an algorithm for finding dominators in an arbitrary directed graph. The algorithm uses depth-first search and efficient algorithms for computing disjoint set unions and manipulating priority queues to achieve a time bound of $O(V\log V + E)$ if V is the number of vertices and E is the number of edges in the graph.

Direction finding circuit arrangement

The Journal of the Acoustical Society of America, 1985
A sonic energy scanning apparatus in which two directional primary sonic energy beams at two different frequencies are radiated into a medium capable of producing nonlinear acoustic effects to produce a third sonic energy beam having a given directional characteristic and a frequency equal to the difference between the frequencies of the primary beams.

Acoustic direction finding systems

The Journal of the Acoustical Society of America, 1987
Hydrophone systems in which the direction of acoustic waves impinging on an array of hydrophones is determined from measurements of the periods between successive zero-crossings of waves detected by the two hydrophones of each of several different pairs of the hydrophones, allowance being made for the fact that the start and finish of such a period may

Direction finding antennas

1992
This chapter discussed the direction finding antennas having two classes to distinguish this. These are (i) Terrestrial or airborne types requiring omniazimuth but limited elevation coverage (ii) Systems for tracking space vehicles and radio stars where essentially hemispherical coverage is required.

Multimode based direction finding

Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002
Direction finding by exploiting higher order modes of a modified biconical antenna is considered. The direction of arrival (DOA) of an incident wave is estimated by using the fact that the different modes have different directional properties. Since only one antenna element is used, the spatial requirements of an array of elements is avoided as well as

Finding the illuminant direction

Journal of the Optical Society of America, 1982
Shading is important for estimation of three-dimensional shape from the two-dimensional image, for instance, for distinguishing between the smooth occluding contour generated by the edge of a sphere and the sharp occluding contour generated by the edge of a disk.
