Low probability of intercept (LPI) has currently become a central issue in modern electronic warfare. In this paper, the problem of task-dependent adaptive radar jamming waveform design based on LPI is investigated. Firstly, the achievable signal-to-interference-plus-noise ratio (SINR) and mutual information (MI) are derived to evaluate the target detection and parameter estimation performance, respectively...
Using high-frequency vector sensor array (VSA) in underwater geoacoustic inversion, the array aperture can be greatly reduced. In this paper, the performance of geoacoustic inversion according to Cramér-Rao bound (CRB) is derived for various seabed parameters and VSA sensor data configurations. Ray tracing acoustic propagation model was used to simulate the vector sensor data. Simulation results showed...
