Recently, a new study of the University of Tel Aviv, Israel, found that a solution inspired by optical coherence breaking imaging technology (OCT), requires little or even zero bandwidth, can accurately create high resolution maps around the radar.
Background
The radar technology started to be designed to identify and track the military objectives in the air. Today, this technology is more commonly used to detect motor vehicles, weather formation and geological terrain.

To date, scientists believe in the accuracy and resolution of radar, and are associated with the frequency range or radio bandwidth used by the device.
Innovation
However, a new study of the University of Tel Aviv University (TAU) found that one program inspired by optical coherence fault imaging technology (OCT), requires little or even zero bandwidth, accurately creates high resolution around the environment around the radar Fig.

Pavel Ginzburg, Professor Tel Aviv University Electrical Engineering, said: "We show a different type of ranging system, which has excellent distance resolution, and almost completely unrelated to bandwidth limit. This new technology has many applications, especially Automotive industry. It is worth noting that existing facilities support our new solution, which means that this program can be implemented almost immediately.
Professor Tel Aviv University of Electrical Engineering, Professor Vitali Kozlov, Professor Rony Komissarov, Professor Dmitry Filonov, jointly leaders and launched this new study. This article published on "Nature Communications" journal on March 29.
Technique
It is generally believed that the radar resolution is proportional to the bandwidth of the used, the wider the frequency range, the more precise the detected object. However, Tel Aviv's researchers showcase the low bandwidth radar can utilize the coherent characteristics of electromagnetic waves, similar performance in the case of lower cost and without broadband signals.
If the two wavegists have a fixed phase difference, the same frequency and the same waveform, they are completely coherent. This new "partial coherence" radar is as effective as the standard "coherent" radar under experimental conditions in discovery goals.

Value
Kozlov said: "Our ideas provide solutions that require high distance resolution and accuracy, but bandwidth limit, such as unmanned automotive industries, optical imaging and astronomy. Today, vehicles on the road are not a lot more Using radar, there is no competition for allocation. However, when each car is equipped with a radar, and each radar needs to occupy the entire bandwidth, what will happen in the future? "
Kozlov said: "We will find that we are in a radio traffic jam. Our solution allows the driver to share available bandwidth without any conflict."
Professor Ginzburg concluded: "Our demonstration is just a series of radio detectors, these RF detectors will explore low bandwidth radar impact on traditional fields. We want to apply this technology until before The field of development, such as rescue operations, sensing individuals burying in the ruins; or street mapping, discerning if children are preparing to pass the road, there is a car hidden behind him.
