Abstract

Provided are electronic warfare system device including: an electronic warfare support unit for receiving a threat signal and generating a Pulse Description Word (PDW) using the received threat signal; an electronic warfare system display for downloading the PDW to perform a threat signal analysis and selecting an electronic attack technique based on the threat signal analysis; and an electronic attack unit for outputting at least one of noise jamming and deception jamming based on the electronic attack technique selected in the electronic warfare system display to perform an electronic attack.

First claim

What is claimed is:

1. An electronic warfare system device comprising:
an electronic warfare support unit for receiving a threat signal and generating a Pulse Description Word (PDW) using the received threat signal;
an electronic warfare system display for downloading the PDW to perform a threat signal analysis and selecting an electronic attack technique based on the threat signal analysis;
an electronic attack unit for outputting at least one of noise jamming and deception jamming based on the electronic attack technique selected in the electronic warfare system display to perform an electronic attack;
a threat signal simulator for generating the threat signal and outputting the generated threat signal to the electronic warfare support unit and the electronic attack unit; and
a scenario simulator for generating a list of threat signals, the threat signal being generated by the threat signal simulator, and operating the threat signal simulator and the electronic warfare system display;
wherein the PDW is downloaded by control of the electronic warfare system display regardless of whether the scenario simulator is operating or not,
wherein a predetermined number of PDWs are stored in a PDW storing plate included in the electronic warfare support unit in order to analyze the threat signal in non-real time,
wherein an electronic attack performed in the electronic attack unit is not performed in real-time by a threat analysis of the electronic warfare support unit but is performed in non-real-time by an electronic attack technique preset in the electronic warfare system display,
wherein the electronic warfare system display sets a beginning condition required for reception of the threat signal by the electronic warfare support unit, and the threat signal analysis is performed based on the generated PDW using the threat signal which is received based on the beginning condition, and
wherein the scenario simulator regenerates the threat signal by operating the threat signal simulator to regenerate the threat signal, and operates the electronic warfare system display to receive the threat signal, in order to check a normal operation of the electronic attack unit, after completing the threat signal analysis by the electronic warfare system display in order to check a normal operation of the electronic attack unit.

2. The electronic warfare system device of claim 1 , wherein the electronic warfare support unit comprises:
an RF receiving plate for receiving a threat signal and converting the thread signal from a high frequency to an intermediate frequency;
a digital receiving plate for converting the threat signal converted into the intermediate frequency into an I/Q signal and generating a Pulse Description Word (PDW) for the threat signal using the I/Q signal;
the PDW storing plate for storing the generated PDW; and
a receiving control plate for controlling the RF receiving plate, the digital receiving plate, and the PDW storing plate.

3. The electronic warfare system device of claim 1 , wherein the electronic attack unit comprises:
a noise generating plate for generating the noise jamming;
a Digital Radio Frequency Memory (DRFM) processing plate for generating the deception jamming;
a high-frequency processing plate for down-converting the received threat signal from a high frequency into an intermediate frequency, or up-converting an intermediate frequency of a deception signal generated in the DRFM processing plate into a high frequency to output the converted signal;
a jamming transmission plate for amplifying and outputting a signal down-converted or up-converted in the high-frequency processing plate and received, or selecting and transmitting at least one of the noise jamming and the deception jamming; and
a jamming transmission plate for controlling the noise generating plate, the DRFM processing plate, the high-frequency processing plate, and the jamming transmission plate.

4. The electronic warfare system device of claim 1 , wherein the electronic warfare system display operates the electronic warfare support unit and the electronic attack unit.

5. The electronic warfare system device of claim 1 , further comprising a signal measurer for measuring signal outputted from the electronic attack unit.
