The use of spaced receivers makes it potential to achieve highly accurate course discovering by measuring the difference in the time of arrival of the signals. Depending on the form of the alerts to be obtained, this measurement could be made by using pulse, correlation, and phase methods. In addition to the comparison methodology, the amplitude technique is used in the evaluation of the envelope of the obtained indicators. This technique can present roughly the identical course-discovering accuracy while at the same time scanning with a slim beam a sector in which there could be several targets. However, an correct resolving functionality for distance entails the usage of indicators with a big bandwidth.
On December 14, 1936, the experimental set detected at as much as 7 m...Read More
