Scientists at St. Petersburg Electrotechnical University "LETI" have developed a laboratory model of a photon radar for monitoring the airspace of an airport, which in the future will become the basis of a new radar complex. According to the developers, the device will be able to detect significantly smaller targets, such as birds in the aerodrome area.
We have created a laboratory model of a photon radar transmitting path. Now the system is already demonstrating stable formation of ultra-wideband signals and a low level of interference (noise) - key parameters for high-precision radar of the future.
The transition to new physical principles of radar and the creation of systems capable of operating in a wider frequency range with minimal noise was implemented by LETI scientists as part of the "Priority 2030" program.
The model includes a laser radiation source, an electro-optical modulator, an optoelectronic generator, a photodetector, and a fiber-optic transmission line simulating a channel to the antenna. The development demonstrated the advantages of the photon approach to radar, where signal generation and processing are performed using light. The new radar represents enormous potential for accurate detection and classification of low-signature reflections.
The creation of an experimental prototype of the first photon radar in Russia is one of the key tasks in the field of radio photonics of the strategic technological project "Development of sovereign technologies and production of components for power electronics and photon information systems". In the near future, scientists plan to complete the creation of the receiving path, proceed to testing the "transmitter-receiver" link and begin developing a special antenna system.
