[0090] Cluster jamming refers to a combination of multiple jamming sources with different distances, angles, and powers. Cluster jamming interferes with the radar's transmit and receive signals. The reason why cluster jamming is difficult to counter is mainly because it has the dual advantages of distributed coordinated jamming and multi-source jamming on the main lobe. It can simultaneously form distributed or centralized multi-point source jamming with controllable distance, angle, and power on the radar's main lobe and side lobes.

[0091] Traditional radar technology and jamming suppression methods lack sufficient freedom and flexibility to counter cluster jamming. Currently, the only way to mitigate the impact of cluster jamming to some extent is by networking multiple radars. However, radar networking inevitably faces a series of problems such as large equipment quantity, low cost-effectiveness, slow data transmission, difficulty in spatiotemporal synchronization, and poor information fusion.
