Because of the direct sequence spread spectrum,the combination of high speed frequency hopping and jumping technolo-gy,the detection of Link16 signal is quite difficult.For a sudden Link16 signal pulse width with strong regularity,double sliding windows Link16 signal detection method based on relevant processing is proposed.This method can realize high sensitivity and high probability detection of Link16 signal in complex electromagnetic environment.Meanwhile,the parameters such as pulse width and bit rate are correctly estimated.Simulation experimental data verifies the correctness of theoretical analysis and the effectiveness of the proposed method.Compared with other methods,the improved dual-sliding window detection algorithm based on correlation processing significantly improves the ability to detect Link16 signals under low signal-to-noise ratio.
