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。
In order to further enhance the integration degree of aviation platform, a highly integrated hardware platform scheme for P / L band of aviation platform is designed. The program directly collects low frequency radio frequency signals below 2 GHz through radio frequency and separates the baseband I / Q signals needed for functions such as detection, communication, navigation, identification and passive reconnaissance in the digital domain, and finally processes the various signals through software , A highly integrated design of co-channel and co-signal preprocessing for functions such as probing, communications, navigation, identification and passive reconnaissance is achieved. The hardware implementation proves that the scheme can effectively reduce the cost and complexity of hardware system design, reduce the system power consumption and promote the application of software radio in the integration of aviation platform.
