Object defense with preventive strike and false targets

Reliability Engineering & System Safety, 2018
Abstract In this paper, optimal strategies for the defender and the attacker are studied. The defender moves first, allocating its limited resources into three diverse measures: launching a preventive strike, building false targets, and protecting the genuine object.

Adaptive cancellation for multiple range false radar targets

2013 6th International Congress on Image and Signal Processing (CISP), 2013
The adaptation of deception electronic attack (EA) for radars has been facilitated by the availability of digital radio frequency memories. This paper proposed a method to employ stretch processing to reject range false targets (RFT) produced by a hostile EA system that present low detection probabilities of the true targets due to high jammer-to ...

False targets vs. redundancy in homogeneous parallel systems

Reliability Engineering & System Safety, 2009
System defense against natural threats and disasters that have a stochastic nature includes providing redundancy and protecting system elements. The defense against strategic intentional attacks can also include deploying false targets aimed at misleading the attacker.

Target acquisition and false alarms in clutter

Optical Engineering, 1995
Recent studies on low-observable target acquisition relate clutter to traditional true- and false-detection performance parameters. This paper presents modified definitions of the target signature and clutter in the image plane and their relation to alternative metrics.

Multiple false targets jamming method based on FIFO

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Efficient active jamming method against modern high resolution radars has been an important research topic in recent decades. The proposed researches introduce many methods to produce false targets jamming or noise depressing jamming. But many of them are somewhat complicated, with too much computing resources, and not possible to be implemented.

Target attribute-based false alarm rejection in small infrared target detection

SPIE Proceedings, 2012
Infrared search and track is an important research area in military applications. Although there are a lot of works on small infrared target detection methods, we cannot apply them in real field due to high false alarm rate caused by clutters. This paper presents a novel target attribute extraction and machine learning-based target discrimination ...

False alarm mitigation techniques for hyperspectral target detection

SPIE Proceedings, 2013
A challenging problem of major importance in hyperspectral imaging applications is the detection of subpixel objects of military and civilian interest. High false alarm thresholds are required to detect subpixel objects due to the large amount of surrounding background clutter.

Target Training Juvenile False Water Cobras (Hydrodynastes gigas)

Proceedings of the West Virginia Academy of Science, 2021
Because all animals have the capacity to learn through operant conditioning and other types of learning, zoos and other animal care facilities have shifted towards the utilization of positive reinforcement training to shape the behavior of animals in captivity.

Optimal Search in the Presence of Poisson-Distributed False Targets

SIAM Journal on Applied Mathematics, 1972
This paper finds search plans, which are optimal in the sense of minimizing mean time to find the target, for several types of searches for a stationary target, in the presence of Poisson-distributed false targets. One must allocate the available effort between broad search to develop contacts and contact investigation to ascertain whether these ...

Identification of false targets in bistatic radar system

Proceedings of the IEEE 1997 National Aerospace and Electronics Conference. NAECON 1997, 2002
This paper presents an identification method of deception false targets in bistatic radar system. On the basis of the data correlation algorithm in bistatic radar system, the identifying rules of the real and the false targets are provided. The experimental simulations show that the method is effective to identify the false targets in EW.
