Analysis of low probability of intercept (LPI) radar signals using cyclostationary processing

open access: yes, 2002
LPI radar is a class of radar systems possessing certain performance characteristics that make them nearly undetectable by today's digital intercept receivers. This presents a significant tactical problem in the battle space. To detect these types of radar, new digital receivers that use sophisticated signal processing techniques are required.

Simulation studies of air transport operational problems [PDF]

open access: yes
An experimental evaluation of the monitored approach procedure for conducting low visibility instrument approaches is described. Four airline crews each flew 16 approaches using the monitored procedure and 16 using a modified standard procedure in a DC ...

Recovery of spinning satellites [PDF]

open access: yes
The behavior of a space tug and a spinning satellite in a coupled configuration was simulated and analyzed. A docking concept was developed to investigate the requirements pertaining to the design of a docking interface.

Recognition of intrapulse modulation mode in radar signal with BRN-EST

open access: yesJournal of Electronic Science and Technology
Neural network-based methods for intrapulse modulation recognition in radar signals have demonstrated significant improvements in classification accuracy. However, these approaches often rely on complex network structures, resulting in high computational

Implementation of a coherent real‐time noise radar system

open access: yesIET Radar, Sonar & Navigation
The utilisation of continuous random waveforms for radar, that is, noise radar, has been extensively studied as a candidate for low probability of intercept operation.

Decision paths in complex tasks [PDF]

open access: yes
Complex real world action and its prediction and control has escaped analysis by the classical methods of psychological research. The reason is that psychologists have no procedures to parse complex tasks into their constituents.
