Ultra-wideband random noise synthetic aperture radar imaging
, 2001 Random noise radars have been analyzed extensively over the past forty years. They were noted for their attractive LPI (low probability of intercept), LPIin (low probability of identification), and LPD (low probability of detection) characteristics ...

Comparative security performance analysis of DSSS and FHSS in underwater acoustic channels.
Underwater Acoustic Communication (UAC) is critical for subsea applications but faces challenges from ambient noise and deliberate interference, such as jamming. This study compares the security and performance of baseline 4-Frequency Shift Keying (4-FSK)
