<P>PROBLEM TO BE SOLVED: To provide a signal identification method of an electronic intelligence receiver which can extract a signal parameter by preventing identification missing or wrong identification due to a multipath signal and unintended MOP. <P>SOLUTION: The signal identification method of the electronic intelligence receiver includes the step of detecting a start time point and an end time point of MOP (modulation on pulse) because of a direct path signal and the multipath signal from a received signal, the step of extracting at least one of a signal strength, a frequency and a phase by utilizing an in-phase component and a quadrature component of the signal in a section from a start time point of the signal to the start time point of the MOP, and the step of extracting a section from the start time point of the signal to the end time point of the MOP as a pulse width of the signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
