对认知无线电用频OODA环的主动有源电子对抗侦察
|
摘要
认知无线电与传统的基于频段预先分配与授权使用的常规通信不同,通过对外界电磁环境的感知来实现对频谱空洞的利用,这一智能化的用频行为具备了观察、调整、决策、行动的OODA环典型特征。针对这一全新的电磁目标对象,在对其用频行为的OODA环通用描述参数归纳总结的基础上,论述了采用主动有源电子对抗侦察方法对此类目标的用频OODA环典型参数进行估计的方法与流程。并以变换域通信系统这一具有代表性的认知无线电设备为对象开展实验,验证了上述方法的有效性,从而为主动有源电子对抗侦察的应用实践与认知电子战的深化研究提供了重要参考。
The cognitive radio is different from the conventional communication terminals based on pre-allocation and authorization of frequency bands. It realizes the utilization of spectrum holes by sensing the external electromagnetic environment. This intelligent behavior for frequency utilization has the typical characteristic of OODA( Observation,Orientation,Decision and Action) loop. This new electromagnetic object is the focus in the paper. After the general description parameters of OODA loop for its behavior on frequency utilization are summarized,the method and process of these parameters estimation by active electronic countermeasure reconnaissance are discussed. Then experiments are carried out on transform domain communication system,which is a representative cognitive radio,and the effectiveness is verified.It is an important reference for the application of active electronic countermeasure reconnaissance and further research of cognitive electronic warfare.
