Engineers from St. Petersburg State University of Aerospace Instrumentation (GUAP) have developed a new type of radar station that simultaneously and accurately determines the speed and range of an aerial target. The documentation was published in the open FIPS database in March 2026.
The main feature of the system is a combined probing signal. The radar combines continuous and pulsed operating modes, uniting the advantages of two classic radar schemes at once.
The continuous mode allows for accurate measurement of target speed using the Doppler effect, while the pulsed mode determines range and separates objects in space. This architecture is particularly effective when dealing with drones, cruise missiles, and low-flying targets.
The developers claim that the system is capable of simultaneously tracking multiple objects without loss of accuracy, even in complex jamming environments.
Separate channels are used for processing the Doppler signal and pulsed reflections. This reduces the probability of errors in high target density.
Classic pulsed radars usually determine distance better, while continuous radars determine speed better. The new GUAP scheme combines both capabilities in one station, eliminating one of the key limitations of traditional radar systems.
