Scientists of the National Research Nuclear University "MEPhI" (NRU MEPhI) have developed the first Russian microelectronic transceiver that provides the operation of "vision" in autopiloted systems. According to them, the use of a new element, characterized by compactness and simplicity, will accelerate the introduction of fully autonomous safe transport.

Technical vision systemsthat use the analysis of radio and optical signals today allow autopiloted vehicles and other autonomous systems to sense the environment almost as well as a person, according to university scientists. The key receiving and transmitting element of such systems is the so - called radio path-transceiver, or sensor, which allows you to transmit, capture and amplify signals. A system of several transceivers of this kind forms the" vision " of autopiloted systems.

The first domestic model of a modern transceiver of this type was developed by scientists of the MEPhI Research Institute. According to them, the new element combines several components on one crystal at once, which will seriously simplify and reduce the cost of creating new vision systems. The use of the new element, scientists believe, will accelerate the practical implementation of fully autonomous vehicles.

"The developed transceiver is designed for radar systems of technical vision in the range of 24-25 GHz with frequency modulation. The device includes a radio transmitter, an emitter and a receiver, " explained the head of the Development Department of the Engineering Center of MEPhIVladimir Klokov. - Our scheme will reduce the size of the radar, which will lead to an increase in the number of sensors, and, accordingly, both to improve the quality of technical vision, and to create a new generation of driver assistance systems with a 360-degree view."

The main advantage of the development, according to scientists, was to increase the level of integration of radar components by combining the emitter, receiver and radio part on one chip. According to the main characteristics of the tested sample, as noted by the creators, is not inferior to existing market analogues.

The transceiver is made on its own technological baseNOC "Nanotechnologies" of NRU MEPhI on the GaAs 150 nm process.

In the future, the research team intends to create a transceiver at frequencies of 75-80 GHz, which will help significantly increase the resolution of radars, as well as develop new microelectronic components using integrated photonics technologies that allow simultaneous analysis of radio and optical signals in technical vision.
