This application relates to a jamming signal generating apparatus. In one aspect, the jamming signal generating apparatus includes a signal analyzer configured to perform measurement and analysis of a radar reception signal, and a radio frequency (RF) source signal output device configured to receive the radar reception signal and to output a video signal by reflecting the measurement and the analysis. The jamming signal generating apparatus may also include a frequency up converter configured to output a jamming signal and a jamming transmission signal measurement device configured to receive the video signal and the jamming signal and to obtain a jamming to signal ratio (JSR).

Jamming signal generating apparatus and method thereof

A chirp noise generation device for a compressed pulse signal includes: a receiving antenna; a signal analysis unit configured to determine whether to perform an electronic attack by analyzing a receipt signal that is inputted through the receiving antenna; and a digital frequency storage configured to store the receipt signal that is inputted through the receiving antenna, to generate a chirp noise by using the receipt signal, to generate a jamming signal by synthesizing the receipt signal and the chirp noise, and to transmit the jamming signal when a control command indicating that the electronic attack needs to be performed is received from the signal analysis unit.

Chirp noise generation device and method for compression pulse signal

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.

Electronic warfare system device with non-real-time threat signal analysis and electronic attack function

There is provided an apparatus for generating a jamming signal for deceiving a transmission/reception device. The apparatus includes a reception unit configured to receive a signal transmitted from the transmission/reception device and a determination unit configured to determine whether or not the received signal is a pulse compression signal. The apparatus further includes a generation unit configured to determine, when the received signal is a pulse compression signal, a deception frequency based on a frequency bandwidth and a pulse width of the received pulse compression signal and generate the jamming signal based on the determined deception frequency.
