受限于探测威力、处理能力、天线孔径等因素,单装性能瓶颈问题凸显,网络化探测将是未来雷达技术发展的重要方向。传统组网雷达采用点迹、航迹层面的数据融合方式,节点相对独立工作,处于“松耦合”状态,协同程度不高。信息有机融合、资源协同管理的信号级“紧耦合”探测框架将是必然趋势。文中就网络化协同探测的相关概念、性能分析、处理方法进行了讨论,重点介绍了信号级“紧耦合”探测框架的各项关键技术,包含网络化雷达接收回波相关性分析、系统误差校正、信号级融合检测、协同目标跟踪定位,以及协同资源分配等,对雷达技术发展具有重要的参考价值。

Restricted by the probing range, processing capacity, and antenna aperture, the performance of a single radar system has almost reached a limit. Collaborative probing scheme will be one of an important directions of radar technology development in thefuture. Traditional netted radar system adopts a data level or track level fusion scheme. Multiple nodes work relatively independent, which can be viewed as a “loose coupling” working mode, and thus cannot be well cooperated. The “tight coupling” probing framework, which incorporates signal level information fusion and resource collaborative management steps, will be an inevitable trend. This paper starts from the concepts, performance analysis and related techniques w. r. t the collaborative probing scheme, and focuses on the key technologies w. r. t. the “tight coupling” probing framework, which includes the correlation analysis of received echoes of netted radar, the system error registration method, the signal level detection method, the cooperative target tracking method, and the collaborative resource allocation method. This paper has important reference value for the development of the radar technology.
