Building a new radar: establishing airport monitoring radar expansion of Runway 4 and Terminal 2, improvements were made regarding
With the continuous development of the airport, the Sinbul A radar was scheduled ASDE for better airport operations. IIAC collected opinions from apron

to be removed at the end of 2022. The new Sammok Radar (PSR/SSR) was controllers and ASDE operators to reflect them into the improvement plan. It
designed to handle issues of the existing radar including weather impact and reviewed how to implement electronic strips for apron control and improve the
shadow areas. In particular, it was designed to minimize the impact of jamming. data fusion processor (DFP) function.
IIAC explored candidate sites for the radar facility, selected one near Asiana With the expansion of Runway 4 and Terminal 2, there was a need to change the

Airlines’ catering facility after a comprehensive comparison of 3 candidates, and map, parameters, and area. IIAC also improved the operating environment by
commenced detailed design and construction. The Sammok radar facility consists adding the electronic flight strip (EPS) and de-icing to the surface monitoring
of a 3-story concrete tower structure, housing radar equipment and an antenna operation system. It also added functions to transfer some roles of IIS Aircraft
tower, designed with considerations for seismic performance and durability. Control to the ASDE. It also installed multilateration (MLAT), fusion processing

of DFP, and improvements in flight plan management functions. The installation
Strengthening surface control accuracy: of MLAT was a priority to detect airplanes and vehicles around the shadow area
improving airport surface control facility with the expansion of Runway 4 and Terminal 2. MLAT compares and analyzes
Airport Surface Detecting Equipment (ASDE) is designed to effectively and time differences in receiving signals from the secondary SSR transponder to detect

efficiently conduct airport surface control. It detects moving objects including the location of the aircraft or moving objects on the ground. It improved accuracy
