A wideband, high-resolution, low-probability-of-detection FFT beamformer

IEEE Journal of Oceanic Engineering, 1994
Navigation of an underwater minefield by a remotely operated vehicle (ROV) or an autonomous undersea vehicle (AUV) requires the detection, localization, and avoidance of obstacles. The sizes of obstacles to be avoided range from the diameter of cables up to the size of other vehicles.

Low probability of detection communications-LPD waveform design and detection techniques

MILCOM 91 - Conference record, 2002
The author defines six typical conventional and low probability of detection (LPD) waveforms and analyzes them against seven detection techniques. Simplified models are presented as examples of each technique and approximate sensitivities derived. These provide a general approach to the designing of waveforms that successfully resist detection.

A metric for defining low probability of detection based on gain differences

Conference Record of Thirty-Fifth Asilomar Conference on Signals, Systems and Computers (Cat.No.01CH37256), 2001
A metric for defining low probability of detection of a communication signal by a radiometer is described. The metric is based on the gain difference G between the communication receiver and the radiometer, which includes their path losses, antenna gains, etc., plus two "mismatch" losses incurred by the radiometer. The probability of detection P/sub D/

Tracking manoeuvring targets with a low probability of detection in clutter

IEE Proceedings F Radar and Signal Processing, 1990
A new technique for tracking manoeuvering targets with a low probability of detection in a cluttered environment is presented. It generalises the (N,M) scan bifurcating filter of Kenefic (1981) so that the life of track branches which do not associate with plots is extended, resulting in improved tracking of targets with a low probability of detection.

Low probability of detection underwater acoustic communications for mobile platforms

OCEANS 2008, 2008
Mobile underwater platforms, such as autonomous underwater vehicles (AUVs), use underwater acoustic communications to form a network for command and control. Direct sequence spread spectrum signaling can be used for multi-access communications. It also provides high processing gain for communications using a low source level.

Automated and Blind Detection of Low Probability of Intercept RF Anomaly Signals

Proceedings of the 30th Annual International Conference on Mobile Computing and Networking
Automated spectrum monitoring necessitates the accurate detection of low probability of intercept (LPI) radio frequency (RF) anomaly signals to identify unwanted interference in wireless networks. However, detecting these unforeseen low-power RF signals is fundamentally challenging due to the scarcity of labeled RF anomaly data.
