Abstract

Low signal-noise-ratio(SNR) target detection is a difficult task in ATR. In this article, a small and weak circular object detection algorithm for forward looking usage is proposed. Firstly the horizon is detected through using the edge operator and large scales of clutters below the horizon are excluded. Then Hough transform based on edge tracing is applied to detect the circular object. The algorithm can be realized in DSP hardware platform in real time, and high acquisition probability is got in tests and experiments.
