DDR-YK8 1, Product Overview The DDR-YK8 radar is a three-coordinate radar with azimuth-beam scanning and elevation beamforming (DBF) in a pulse Doppler configuration, primarily designed for detecting and locating low-altitude aircraft. It can precisely determine the spatial position of targets and, when integrated with electro-optical systems, can be cascaded with countermeasures such as jamming systems, laser weapons, and navigation spoofing devices. 2, Specification 1.
