Abstract: 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.
