The medium-range low-altitude surveillance radar features robust clutter suppression capability, enabling it to effectively filter interference signals and reliably detect and lock onto low-altitude and ultra-low-altitude targets, even in strong clutter environments caused by terrain, sea waves, or urban backgrounds. This characteristic ensures stable and continuous detection performance in complex ground environments and coastal areas.

The key to achieving this performance lies in its superior angular resolution, particularly in elevation, which reaches ≤0.5°. This fine elevation resolution allows the radar to effectively distinguish genuine ground-skimming targets from ground-reflected clutter in the height dimension, significantly reducing false alarms and ensuring clear, reliable continuous tracking and surveillance of low-altitude penetrating threats.
