BOEING LOBE SWEEP INTERFEROMETER SYSTEM
Abstract
A lobe sweep interferometer system is described. Continuous measurements are made of the intensity of the total coherent noise received from the sun at 221 mc and the phase difference between the signals from two antennas. A phase lock method of maintaining a 1 kc difference between two mixer injection signals at 251 mc is described. A phase compensator is discussed in which a fixed phase relationship is maintained between a reference signal and the 1 kc signal resulting from a fictitious source at the predicted position of the sun. It is shown that the use of the compensator simplifies angle measurements of burst positions and facilitates measurement of the position of the radio center of the sun. A discussion is given regarding the interpretation of the received data to provide position measurements of bursts in relation to solar co-ordinates. The effects of fringe blurring and correction for an extended source distribution are discussed. Several factors affecting the precision of position measurements are presented.
