DLD-100C

The DLD-100C is an operating in D-Band monopulse secondary surveillance radar (MSSR) that has obtained the certificate of authority issued by the Civil Aviation Administration of China (CAAC). The radar adopts series advanced technologies such as high-gain array antenna with large vertical aperture, monopulse azimuth angle measurement, full-solid state and digital IF receiver, with Mode S (EHS), complete online BITE function, seamless automatic switchover function and two identical redundant interrogator channels configuration. It can provide information of range, azimuth, code, altitude and special status of civil aviation aircrafts (with transponder). It supports the interrogation modes 1, 2, 3/A, B, C, D and S, complies with ICAO specifications, and is widely used in modern Chinese air traffic control systems.
