Abstract: Aiming at the situation of heavy traffic in civil airport, complicated scene in airport and complex weather (foggy
weather), and this paper introduces an airport surface movement radar based on adaptive target detection
technology. The signal processing design mainly adopts adaptive STC (Sensitivity Time Control) and adaptive
clutter detection technology to improve the target detection probability (>97%), reducing the false alarm
probability (<3×10
-7
) and improving the system's anti-interference and environmental adaptability. That can
improve the airport operating efficiency while ensuring the flight safety of the aircraft, meeting the requirements
of civil aviation CNS equipment.
1INTRODUCTION
With the development of economic activities, the
rapid development of air transport industry and the
growing fleet size of airlines have resulted in the
rapid increase of aircraft take-off and landing
frequency in the airport. The frequency of aircraft
and motor vehicle movements has also become
increasingly frequent simultaneously. In the area of
airport surface, the probability of collisions between
take-off, landing and taxiing has greatly increased
as a result of the obstruction of the air traffic
controllers and other irresistible factors such as the
weather (rain, snow and fog). Therefore, it is
becoming increasingly prominent to effectively
solve the problem of traffic congestion and conflicts
in the airport, and the management of aircraft and
mobile vehicles at airports is becoming increasingly
important.
As an important equipment of civil air traffic
control field, Surface Movement Radar (SMR) not
only can detect and locate the target in real time, but
also can accurately obtain the information such as
the movement trajectory of the aircraft and vehicle
in the conflicts of aerodrome surface. However it
also appeared many problems in the course of
operation. In some airports, the effective reflection
area of buildings is large, and small targets
(vehicles, etc.) near tall buildings are easily lost.
Airports with damaged clearances have a serious
impact on the increase of false targets due to
complex electromagnetic environment, crosstalk
and multipath system performance. Some airports
have poor weather conditions, radar systems can
easily detect false targets and lose real targets,
greatly reducing SMR’s performance.
At present, they mainly use TERMA from
Denmark and INDRA from Spain in the domestic
airports. In recent years, as the state vigorously
promote the civil aviation CNS equipment
localization process requirements, the domestic
SICHUANG company of CETC-38th and other
companies have successfully developed a surface
movement radar system and has achieved "Civil
Aviation Air Traffic and Communications
Navigation Surveillance Equipment Provisional
License". These devices in the licensing process of
certification, the system requires to be strictly
validated and system tested to ensure that their
systems performance and reliability meet the
relevant technical requirements.
