Abstract

The reliable long-range detecting and tracking of fast moving targets is a crucial problem in shooting range tests. The target signal received by IR tracking equipment usually changes instantaneously in both time domain and in the space domain, and it will by buried in the background noise more seriously when the projected target moves farther. A novel method of target signal detection is proposed by using nonlinear feather accumulation, 2D signal-feature joint detection, temporal association, and synthetical competition decision techniques. The developed algorithm can not only overcome the detection missing problem resulted from the spatial and temporal violent undulating of target signal, but also guarantee along-range optimal detection results. It has been used to increase the target detection range greatly and can acquire the weak target signal effectively even under about -3dB signal to noise ration (SNR).
