Abstract: | Radar signal in pulse modulation identification is the important content of radar reconnaissance. Multiple type modulation signals can be identified and the modulation parameters can be extracted by the instant frequency identification technique. Under certain signal to noise ratio, this method has high identification ratio. It is suitable for high speed realization in the radar reconnaissance digital receiver, because it has a simple algorithm. |
