摘　　要：相位编码调制信号是一种典型的脉冲压缩信号,广泛应用于脉冲压缩体制的低截获概率雷达中。获取相位编码信号的编码规律对单站无源定位与跟踪十分重要。推导了基于连续小波变换的相位编码信号相位调制函数的估计算法,能得到相位编码信号的相位调制函数的正确估计。计算机仿真结果证明了算法的有效性。PCM signal is a kind of pulse compression waveform which is widely used in low probability of intercept adopting pulse compression radar system. It is important to gain the modulation rules of phase code modulation signals for the passive locating and tracking system of single observer. An algorithm is deduced based on continuous wavelet transform, The phase modulation function of PCM signal is precisely obtained by this algorithm. The performance of this algorithm is effectively proved by the computer simulation results
