Overview

The algorithm suppresses static clutter in UAV perception, significantly improving target distinguishability.

Key Points

  • Effective in suppressing static clutter, enhancing the visibility of dynamic targets.
  • Demonstrates better performance than existing methods in low-speed group target perception.
  • Utilizes a circular fitting algorithm and OFDM echo channel characteristics.
  • Introduces an energy ratio to quantitatively evaluate clutter suppression effects.
