AI Technical Summary
Existing target two-threshold detection methods have low algorithm adaptability in radar, are difficult to port to server platforms, misjudge clutter as targets, have a high false alarm rate, and lack secondary detection, which makes it easy for problems such as loss of tracking, wrong tracking, and missed tracking to occur during target tracking.
A target two-threshold sliding window detection method based on two-coordinate radar is adopted. By setting a sliding window in a planar coordinate system, the sliding window is updated and small module detection is performed using the pulses detected by CFAR. The target status is judged and clutter is filtered to achieve secondary detection.
It improves the reliability and false alarm rate of radar target detection, enhances the controllability and portability of target detection, is applicable to multiple hardware platforms, reduces the false alarm rate, and improves the clarity of target display.
