Prospects of the radiophotonics application in ground-based long-range detection radars

The application of radiophotonic technologies in radar, according to many researchers and developers, is able to reach qualitative gain in parameters of radio information systems and complexes. However, these improvements are mainly pertinent to radars operating above 20 GHz, what implies a relatively short range. At the same time, the application of radiophotonics in "low-frequency" radars that solve tasks of detecting and observing objects at long distances, including space objects, attracts much less attention. Given importance of monitoring the near space with its extreme overload of targets and need to find new effective system, technical and technological solutions for creating highly informative radars, it is worth to consider making use of radiophotonics technologies in long-range detection radars. This paper aimes to estimate benefits radiophotonics technologies may suggest to long-range radars features. The prospects of the application of radiophotonic technologies in radar are estimated from the standpoint of qualitative gain in energy and information features for the tasks of detecting space targets and evaluating their coordinate and non-coordinate parameters. This enables us with a more reasonable approach towards new system engineering, design, and technological solutions into both existing and developed radars that might improve monitoring near-Earth space.
