Secondary Surveillance Radar

• Full Mode S capability such as normal surveillance, enhanced surveillance, collaborative surveillance and datalink communications, etc.
• Dual-redundant structure design ensures 24-hour, all-weather operation with automatic and full-solid-state transmitter and digital receivers.
• Calibration for receiving channel amplitude and phase coherence with accurate and flexible digital.
• Optimized BIT function designed to realize online or offline fault diagnosis. Fault can be located to the main functional modules.
• Highly integrated design with reduced number of customized components.
