| Abstract: | To solve the weak target detection under the clutter background,combined with dynamic chaotic model,the chaotic property of the laser echo signal is discussed and a novel algorithm is presented based on chaotic signal detection using neural network predictor.The weak signal in laser clutter background can be detected by means of the prediction error.The simulated results show the algorithm is effective. |
