![]() After some refining, the Weather Bureau rolled out its first network of radars in 1959.Īs technology continued to improve, radar did the same: newer, more reliable computers quickly became available for the most accurate data possible. Weather Bureau scientists and technicians recognized the strengths and limitations of these older systems and began to modify and update the technology to better suit the needs of short-term forecasting. However, much of the donated equipment was specifically designed for military use. Upon further investigation, it was determined these “echoes” were caused by precipitation thus, the idea to use radar technology for meteorological purposes was born.Īt the end of the war, the military donated at least 25 radar systems to the Weather Bureau, marking the beginnings of the US weather radar system. Using this groundbreaking technology to scan the skies for incoming airplanes, radar analysts noted that, during periods of heavy or intense weather, the radar would return strange signals and patterns. However, the use of radar for weather observations was discovered unintentionally. In order to gain an advantage in the war, the US and Great Britain decided to pool all of their radar information, resulting in the development of the earliest modern radar. With the United States’ entry into World War II, the need for accelerated radar development was fully realized, primarily by Allied powers. ![]() From this baseline discovery, radar technology, knowledge, and experimentation began enthusiastically. He discovered that electromagnetic waves could reflect off of various objects, and even be focused into beams by reflectors. ![]() In fact, the fundamental principles of radar were first observed in late-19th century Europe by Henreich Hertz, a physicist. It is true in a way, but only to the extent that technicians and aviators in the war streamlined the technology and produced systems in great quantities. While it is commonly assumed that radar was a byproduct of military necessity in World War II, that isn’t the whole story. Though today’s radar has been adapted for meteorological application, the science behind this revolutionary technology came into being more than a century ago. PB - Institute of Electrical and Electronics Engineers Inc.A crucial element of modern meteorology, Radio Detection and Ranging, commonly known as radar, is used today in forecasting weather events like rain, sleet, snow and tornadoes. T3 - 2023 57th Annual Conference on Information Sciences and Systems, CISS 2023īT - 2023 57th Annual Conference on Information Sciences and Systems, CISS 2023 We demonstrate that this pre-processing and training scheme successfully allows for the detector to learn Doppler intolerant waveforms such as the noise waveforms. The training data is then augmented with Dopplershifted waveforms, such that this Doppler shift appears in the phase-aligned data. In order for the network to successfully learn the noise waveform, a pre-processing step of phase alignment is performed on the data to allow the neural network to establish a pattern. The concept of noise waveform radar is explored, and the core issue of Doppler tolerance is addressed. We demonstrate that this pre-processing and training scheme successfully allows for the detector to learn Doppler intolerant waveforms such as the noise waveforms.ĪB - This work analyzes neural network learning as it pertains to noise waveform radar detectors.
