Experimental Demonstration of Quantum Low Probability of Intercept for Ultra-Secure Communication [PDF]
, 2023 Secure communication systems utilize encryption with shared keys between the sender and receiver of the encrypted message. For added security, the encrypted message can be hidden within a significant amount of noise so that the eavesdropper could not ...

A Study on Antenna of Low-Probability of Intercept for LOS Datalink System [PDF]
Journal of the Korea Institute of Military Science and Technology, 2021 In this paper, an array antenna for LOS datalink for mounting UAV(Unmanned Aerial Vehicle) of low-probability of intercept is presented. For low RCS, radome was designed by conformal form, and other components were inserted into the UAV. The antenna of the transmitter and receiver are each composed of 12×12 array antennas, and include a beam steering ...

Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal
Sensors, 2018 The linear stepped frequency and linear frequency shift keying (FSK) signal has been widely used in radar systems. However, such linear modulation signals suffer from the range–Doppler coupling that degrades radar multi-target resolution.
