Research On Aircraft Environment Surveillance System Modeling And System Design

Integrated Surveillance System(ISS)is designed to conduct flight operations in a safe and efficient manner,and it is the key component of the aircraft Communication,Navigation and Surveillance avionics,which includes the airborne weather radar(WXR),terrain awareness and warning system(TAWS),traffic collision avoidance system(TCAS)and mode S transponder.This paper focuses on design of integrated surveillance system simulator under integrated modular avionics(IMA)architecture.Compared with the traditional federated avionics architecture,this paper designed the integrated surveillance system simulator,and built the data generator,simulator,and the display and control system simulation platform,conducted the simulation of the basic functions of integrated surveillance system.By fusing input trajectory data of ISS that from different sensors,the false positive and false negative alert rate are reduced.By using comprehensive decision-making of ISS subsystem outputs,some of the potential threats can also be detected.Finally the rationality and feasibility of the simulator design scheme is verified.
