Aiming at the detection of small moving targets in complex background, this paper designs a real-time moving small target detection system using time-domain low-pass filtering and multi-frame correlation method.The system is suitable for slow changing background or relatively static background environment, Under the condition of constant false alarm probability, the position of small target can be well identified, and the contour of small target can be identified by adaptive thresholding.
