| 摘 要： | 针对在非合作突发通信信号检测中,已有的各种检测方法均未能充分利用信号的频域连续性的问题,提出了一种新的检测方法,利用信号的频域连续性,在频率和带宽二维进行频域能量累积,搜索最大值并检测.理论分析和仿真均验证了此方法优于Power-Law方法 2 dB以上.

| Abstract: | In the fields of detecting non-cooperative burst communication signals, the existing various detectors have failed to make full use of the continuity of the signals in frequency domain. Employing the frequency domain continuity of signals, a new detector is presented in this research. It searches the maximum energy by sliding in both carrier location and bandwidth. Both theoretical analysis and simulations illustrate that, the proposed detector outperforms that of Power-Law method more than 2 dB. |
