SIGNAL DISCRIMINATING METHOD OF ELINT RECEIVER
First Claim
Patent Images
1. A signal discriminating method of an electronic intelligence receiver, comprising:
- (a) detecting a start time and an end time of modulation on pulse (MOP) due to a direct path signal and a multi path signal from a received signal; and
(b) extracting at least one of signal strength, frequency, and phase by using in-phase component and quadrature component of the signal in a time from a start time of the signal to a start time of the MOP.

Abstract
Provided is a signal discriminating method of an electronic intelligence receiver. The method includes: detecting a start time and an end time of modulation on pulse (MOP) due to a direct path signal and a multi path signal from a received signal; and extracting at least one of signal strength, frequency, and phase by using in-phase component and quadrature component of the signal in a time from a start time of the signal to a start time of the MOP. As a result, the present invention can prevent faulty discrimination or no discrimination of a signal due to a multi path signal and an unintended MOP to extract signal parameters.
