Non-Cooperative Detection of Frequency-Hopped GMSK Signals [PDF]
Many current and emerging communication signals use Gaussian Minimum Shift Keyed (GMSK), Frequency-Hopped (FH) waveforms to reduce adjacent-channel interference while maintaining Low Probability of Intercept (LPI) characteristics.

Hiding Information in Noise: Fundamental Limits of Covert Wireless Communication [PDF]
Widely-deployed encryption-based security prevents unauthorized decoding, but does not ensure undetectability of communication. However, covert, or low probability of detection/intercept (LPD/LPI) communication is crucial in many scenarios ranging from covert military operations and the organization of social unrest, to privacy protection for users of ...

Implementation of a coherent real‐time noise radar system
A real‐time noise radar system is implemented, and relevant hardware and system aspects of noise radar implementation are presented. The constructed system processes data continuously with 100 % duty cycle, and it can do so indefinitely while operating with 200 MHz bandwidth, processing a range of up to 8.5 km, and integrating each coherent processing ...
