摘　　要：介绍了基于正弦波频率估计的脉内特征参数估计方法,并与数字正交法相结合,解决了编码信号频率估计模糊问题。对单频信号、线性调频信号、二相编码信号、四相编码信号进行了脉内特征分析,给出了仿真结果。A method based on sine-wave duced. Combined with digital orthogonal cy estimation ambiguity of coded gle-frequency, and those simulation results are giv signals en, frequency estimation for in-pulse fine feature analysis is introalgorithm, the method is used to solve the problem of frequensignals. The in-pulse feature analysis is made on the signals with sinrespectively being linearly frequency-modulated, phase coded. The
