Abstract

To the problem of the target detection when the frequency of target line spectrum signal is unknown, the article proposes a target detection weighted method based on amplitude. When the target radiation signal has a stable line spectrum signal, the gain of this method is consistent with the gain of line spectrum being known. When the target radiation signal has only broadband signal, the gain of this method is consistent with the gain of broadband energy integral. Numerical simulation has showed that comparing this method with the way without amplitude weighting, this method has better detection performance and better robustness. This method provides some reference for subsequent research.
