Information theoretic limits on non-cooperative airborne target recognition by means of radar sensors
- Computer Science
It is demonstrated that information theory, and specifically the concept of mutual information (MI) can be used to predict the maximum target recognition performance for a given radar concept in combination with a given set of targets of interest.
Increasing Radar Target Information
- Computer ScienceJournal of Navigation
Attention is now being directed to the possibility of using wide-band signals, either to improve target detection and location for an array of a given size or to obtain additional information about the nature and behaviour of the radar target itself.
Information resolution of joint detection-tracking systems
- Computer Science2011 12th International Radar Symposium (IRS)
The realistic meaning of information resolution is presented by relating it to the radar signal detection process by determining the minimum distinguishable threshold of the information resolution under the minimum probability of error criterion.
Constant information radar for dynamic shared spectrum access
- Computer Science, Business2015 49th Asilomar Conference on Signals, Systems and Computers
The constant information radar is derived, a measure of target uncertainty and thus information transfer for a given tracking loop period, which can be used to modulate radar emission rate to minimize shared spectrum impact to communications networks.
Radar measurement as an operator problem
- PhysicsDefense + Commercial Sensing
There is a connection between radar theory and the formalism of quantum mechanics that has not been explored by many radar engineers and this approach may be the key to understanding the underlying interactions found within return signals.
Wideband ambiguity function in radar and navigation systems
- Computer Science2014 IEEE 3rd International Conference on Methods and Systems of Navigation and Motion Control (MSNMC)
The new nonparametric variant of the ambiguity function, which is based on the copula notion, is discussed and can be used for the signal synthesis and detection in different electronic systems for signals with an unknown spectrum and probability density function.
The radar system and information flow
- Computer Science2010 2nd International Workshop on Cognitive Information Processing
The information flow through a radar system channel is studied for various component design choices including the radar measurement function, signature feature selection, and classifier decision…
Impact of quantization on passive radar target detection
- Computer Science
The dynamic range requirements of a passive radar system are investigated and the impact of analogto-digital converter (ADC) quantization on system performance is shown and how many ADC bits are required in each channel is analyzed.
