Low-Interception Waveform: To Prevent the Recognition of Spectrum Waveform Modulation via Adversarial Examples [PDF]
URSI GASS, 2021, pp. 1-4, 2022 Deep learning is applied to many complex tasks in the field of wireless communication, such as modulation recognition of spectrum waveforms, because of its convenience and efficiency. This leads to the problem of a malicious third party using a deep learning model to easily recognize the modulation format of the transmitted waveform.

Generation of pseudo-random sequences for noise radar applications [PDF]
, 2014 Noise Radar Technology (NRT) is nowadays a promising tool in radar systems. It is based on the transmission of waveforms composed of many noisy samples, which behave as LPI (Low Probability of Intercept) and antispoofing signals.

Research on the Guidance Method of Radar-Type Anti-Aircraft Missile against Ultra-Low-Altitude Target [PDF]
Hangkong bingqi, 2023 In view of the problem that radar-type anti-aircraft missiles are affected by the multipath effect when intercepting ultra-low-altitude targets, the radar seeker looks down to detect the target, which seriously reduces the tracking accuracy, and the ...
