Detectability models for multiple access low-probability-of-intercept networks [PDF]

open access: yes, 2000
Increased demands for communications in the tactical battlefield have driven the development of multiple access low-probability-of-intercept (LPT) networks. Most detectability studies of LPI networks focus on the individual links of the network, in which

Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal

open access: yesSensors, 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.
