The invention discloses an ADS-B weak signal detection device and method based on multi-feature fusion. According to the ADS-B weak signal detection method and device based on multi-feature fusion, the conventional mode that an existing signal detection system mainly takes energy features of signals as the basis and adopts threshold detection is broken through, multi-feature information containedin received signals are utilized to solve the problem that the detection performance is reduced due to weakening of the target signal state information under a strong noise interference condition.
本发明公开了一种基于多特征融合的ADS‑B微弱信号检测装置及方法。本发明各实施例的基于多特征融合的ADS‑B微弱信号检测方法及装置,突破现行信号检测系统主要以信号的能量特征为依据,采用门限检测的常规模式,利用接收信号本身包含的多特征信息,改善强噪声干扰条件下由于目标信号状态信息弱化导致的检测性能下降的问题。
