IEEE/ICACT20230135 Question.5 Questioner: franklinlu888@outlook.com 2023-02-21 오후 3:42:32	IEEE/ICACT20230135 Answer.5 Answer by Auhor yjk1425@163.com 2023-02-21 오후 3:42:32
A very nice presentation! What is the characteristic of the fuze jamming signal? Are these characteristics can aid the recognition?	Firstly, the power of the fuze jamming signals will be higher than some traditional communication jamming signals. Secondly, the fuze jamming signal is very close to the fuze signal in frequency domain, like some advanced DRFM-based jamming signals, which are real fuze signals in nature. Therefore, in order to recognize quickly and accurately, we need at least two dimensions to obtain the characteristics of the jamming signals. In the time-frequency domain, we can clearly see the difference between these jamming signals and fuzing signals due to the high power of the jamming signals, and the difference can also be seen from the whole time-frequency diagram if they are close in power.
