Description
Yonggan Zhang, Liyong Ge, and Yong Wu tackle false signals in a 2025 radar paper. Passive radar listens with signals from radio or phone towers, which makes it cheap and hard to jam. It needs a clean copy of the source signal, but echoes from targets can leak into that copy.
The leak creates ghost peaks that share a target's speed shift but sit at the wrong range, hiding real targets. The authors trace how the ghosts form and then propose a fix. Their fix checks patterns across many frames and masks suspect spots around strong anchors, avoiding the heavy rebuild steps of older methods.
