一种P/L频段高度综合化航空平台的设计

为进一步提升航空平台综合化程度，设计了一种用于航空平台的P/L频段功能高度综合化硬件平台方案。该方案通过射频直接采集2 GHz以下的低频射频信号，在数字域分离出探测、通信、导航、识别以及无源侦察等功能所需基带I/Q信号，最后通过软件完成各种信号的功能处理，实现了对探测、通信、导航、识别以及无源侦察等功能共信道和共信号预处理的高度综合设计。硬件实现验证了该方案能够有效降低硬件系统设计的成本和复杂性，降低系统功耗，有力推进了软件无线电在航空平台综合化中的应用。

Design of a highly integrated P/L band aviation platform

In order to further improve aviation platform integration,a P/L band highly integrated hardware scheme for aviation platform is designed. In the scheme radio frequency( RF) signal under 2 GHz is ac-quired directly through RF and in the digital domain baseband I/Q signals for detection,communication, navigation,identification and passive reconnaissance are separated, and finally the functions of various sig-nals are completed with software,thus implementing highly integrated design of co-channel and shared sig-nal preprocessing of such function as detection,communication,navigation,identification,and passive de-tection. Hardware implementation shows that this scheme can effectively reduce the cost and complexity of the hardware system design,reduce the power consumption of the system,and strongly promote the applica-tion of software radio in aviation platform integration.
