摘要
飞机环境监视系统是保证航空器全飞行过程安全航行的重要航电子系统。针对系统的开放性、可扩展性和低总耗需求,首先提出了基于传感器开放式系统架构(Sensor Open System Architecture,SOSA)的系统功能架构,从系统运行支持、发射/接收器、信号/目标处理、分析与开发、信息传达、管理服务等6个顶层模块定义了49个标准功能组件,实现功能域的解耦。设计了基于像素级、特征级和决策级融合的机载多源融合感知算法框架,实现对合作目标和非合作目标的综合态势感知。提出了由零中频体制通用射频收发通道、基于“平台+APP”的数据处理资源平台等构成的分布式综合化硬件架构,实现硬件资源的集约化和软件功能的增量扩展。硬件平台的试验评估表明,分布式架构相比联合式和集中式架构,系统在重量、体积和功耗方面分别提升了49%和34%,同时具备更好的可靠性和开放性。
Aircraft environmental surveillance system is an important avionics subsystem to ensure the whole flight process of aircraft.According to the requirements of openness,scalability and low total consumption,the system function architecture based on sensor open system architecture(SOSA)is proposed.Forty-nine standard functional components are defined from 6 top-level modules,such as system operation transmitter/receiver,signal/target support,processing,analysis and development,information management transmission,services,etc.,to realize the decoupling of functional domains.The airborne multi-source fusion perception algorithm framework based on pixel-level,feature-level and decision-level fusion is designed to realize comprehensive situational awareness of cooperative and non-cooperative targets.The distributed integrated hardware architecture composed of zero-IF system universal RF transceiver channel and data processing resource platform based on“platform+APP”is also proposed to realize the intensification of hardware resources and the incremental expansion of software functions.The test and evaluation of the hardware platform shows that the distributed architecture has increased the weight,size and power consumption by 49%and 34%respectively compared with the joint and centralized architectures,and has better reliability and openness.
