A Detection Method for LFM Signal Embedded in NMA Interference Using Signal Phase Matching Principle
基于相位匹配的噪声调幅干扰下LFM信号检测

On the basic of Signal Phase Matching Principle (SPMP), a detection method for Linear FM (LFM) signal embedded in Noise AM (NAM) interference is presented. The formula for estimation the carrier frequency of noise AM interference is derived, and the signal phase is matched using the carrier frequency of interference, then LFM signal is detected based on least squares of signal phase matching. The simulation shows that the proposed method is efficient.
