Doppler radar information tracking method for small targets based on slow low-altitude

The present invention discloses a radar Doppler information Low Altitude slow tracking method based on small target, comprising the steps of: (1) each of the radar target point i-1 st and i th scan track sets from condensed, and wherein each reject clutter false alarm point; (2) set the target point of the trace i-1 st and i th point to eliminate clutter and false alarm scan, track bar may establish Q; continuous radar i + 1-st and i + 2 scan, and the target track may be updated each point interconnect track number, the track number of the target network point of less than 3 may eliminate the track, the track may then remove the false Air trace, to obtain a target track initiation article D success; (3) i + r of the radar scan, track, and update each target frame dropping out of the starting number of successes, the initial target if successful track number of dropped frames is not greater than 3, r is incremented by one so that the number of iterations, the initial success of the radar to track a target track, on the contrary, the radar tracking successfully stopped the initial target track.
