A system for recording the direction of arrival and intensity of static on short waves is described. The system consists of a rotating directional antenna array, a double detection receiver and an energy operated automatic recorder. The operation of the system is such that the output of the receiver is kept constant regardless of the intensity of the static. Data obtained with this system show the presence of three separate groups of static: Group 1, static from local thunderstorms; Group 2… Expand
The Determination of the Direction of Arrival of Short Radio Waves
In this paper are described methods and technique of measuring the direction with which short waves arrive at a receiving site. Data on transatlantic stations are presented to illustrate the use ofExpand
Electrical Disturbances Apparently Of Extraterrestrial Origin
Electromagnetic waves of an unknown origin were detected during a series of experiments on atmospherics at high frequencies. Directional records have been taken of these waves for a period of over aExpand
Radio Waves from Outside the Solar System
IN a recent paper1 on the direction of arrival of high-frequency atmospherics, curves were given showing the horizontal component of the direction of arrival of an electromagnetic disturbance, whichExpand
A Multiple Unit Steerable Antenna for Short-Wave Reception
This paper discusses a receiving system employing sharp vertical-plane directivity, capable of being steered to meet the varying angles at which short radio waves arrive at a receiving location. TheExpand
Microwave Radiation from the Sun
During the summer months of both 1942 and 1943, the writer and certain of his associates observed a small but measurable amount of microwave radiation coming from the sun. This appeared as randomExpand
Cosmic Radiations at 5 Metres Wave-length
THE discovery of electromagnetic ‘noise’ radiations at radio frequencies was first made by K. G. Jansky1 who, in a series of measurements at about 20 Mc./s. (λ ≈, 15 m.) was able to establish theExpand
The Maximum Range of a Radar Set
Formulas are derived which may be used to calculate the maximum range of a radar set. It is shown that the maximum range obtainable with a given radar set depends upon (1) the energy in the pulse,Expand

This thesis describes the design of several components of a proposed VHF radar system for the Department of Physics and Astronomy of the University of Canterbury, New Zealand. A suite of software forExpand
Low frequency array (lofar)- potential and challenges
TLDR
In this chapter the signal processing aspects on system level will be presented and methods to image the sky will be given and the mapping of these concepts to the LOFAR phase array radio telescope will be present. Expand
Cosmic Radio Noise
Publisher Summary This chapter discusses the fact that because noise is the factor which limits the detectability of radio communication signals, it is important that the characteristics of cosmicExpand
