Rostec’s Rosel holding has developed a solution for detecting stealthy objects, including fiber-optic drones, a three-dimensional passive coherent radar (3D PCR). Its key advantage and difference from traditional radars are in the absence of reradiation. This makes the product invisible for radio reconnaissance to protect the device and operator against detection. 

The device records signals reflected from the target, that are emitted by external transmitters, rather than by radar station transmitters — broadcast (radio and TV) transmitter signals. 3D PCR analyzes the phase and amplitude of received signals providing exact coordinates of the detected potential hazard — by azimuth, range and altitude. The radar can ‘see’ light aircraft at a range of several tens of kilometers. 

By detecting a wide variety of stealthy objects, including fiber-optic drones, 3D PCR can effectively control air, above-water and ground space of the protected object. 

The device doesn’t need any licensed frequencies. The radar can be energized by low-voltage power supply compared with active radars and radio-optical systems. A set of advanced engineering solutions in the field of passive coherent location can use the existing infrastructure and reduce the system operating cost.
