NATIONAL WEATHER SERVICE DOPPLER RADAR IN MOTION PORTABLE
These radars combine all the benefits of both long range and high velocity ability’s. This is when the more common Pulse-Doppler was introduced. Once the new digital technology became readily available, the radars became more specialized, lighter, and even more affordable.

Even now, the radars the police use today are a smaller and more portable version of a Doppler radar. This includes the ability to detect motion from any vehicle while in combat in any type of weather and at any time. Now with the use of modern Doppler systems, they are extremely light and mobile enough for ground surveillance. As a result, the Doppler improves, and continues to be refined into a lighter and more efficient system. This changed in the 1970’s when the Doppler no longer relied on the large analog filters, waveguides or amplifiers. All this extra weight limited there with daily activities, causing the military aircraft to go only on night operations, heavy weather events or jamming situations however, they still wanted to take advantage of this technology regardless of the weight the military went ahead and implemented the use in the early 1940’s. These older radars required the use of large bulky equipment to work the radar. The early Doppler radars relied on large analog filters to get any usable performance data use from them. This effect would later be highly developed to create radars specialized in specific scientific fields. A phenomenon we would come to know as the Doppler Effect. This would work the same if the source of the wave were to move away thus the waves would decrease along with the sound of the pitch. However, if the source of the sound came closer, then the number of waves reaching the ear would increase as well as the pitch. When a person or object is not moving, the tone would generally stay the same unless the object is moving at right angles. The different audio frequencies waves observed alongside of the actual frequency emitted in relation to the person or object moving closer to or farther away from the source of the frequency waves.Äoppler determined the frequency of the waves reaching the ear in a certain measure of time and could be used to determine the tone or pitch that is heard. He discovered there was a way to see the difference between different frequency waves. An Austrian physicist named Christian Doppler created the Doppler in 1842 and thus named after him. For example, the radar originally created in the beginning was for the military use primarily. Although, the weather is the most popular use of this type radar, many people still know little else about them. What do you think about when someone mentions a Doppler radar, what comes to your mind? For most people, they think about the weather channel on the television.
