摘要
针对目标辐射线谱信号未知时目标检测问题,提出基于幅值加权的目标检测方法。在目标辐射信号具有稳定线谱情况下该方法与已知线谱检测法增益一致;在目标辐射信号只有宽带信号情况下该方法与宽带能量积分检测法增益一致。数值仿真表明,与未进行幅值加权法相比,该方法检测性能得到提高,且鲁棒性较好。该方法对相关研究具有一定参考价值。
For target detection,in case of that the frequency of target radiation line spectrum is unknown,a target detection method based on weighted amplitude was proposed. When the target radiation signal has a stable line spectrum,the gain of this method is consistent with the gain of known line spectrum method. When the target radiation signal has only broadband spectrum,the gain of this method is consistent with the gain of broadband energy integral method.Numerical simulations show that comparing with the way without amplitude weighting,the method has better detection performance and better robustness. The method provides some reference to subsequent research.
