Waveform-Agile Sensing: Opportunities and Challenges available in PDF, EPUB and Kindle. Continuing advances in device technologies are producing active sources that are increasingly agile in their waveform transmission capabilities. Additionally, modern receivers are generally designed to support adaptive processing. This combination presents rich opportunities for new sensing methodologies that exploit agility of both transmitter and receiver to yield improved performance in such applications as detection, classification, and tracking. This paper outlines some of these opportunities and sketches some challenges entailed in realizing these opportunities and approaches being brought to bear on these challenges.

Advances in Waveform-Agile Sensing for Tracking available in PDF, EPUB and Kindle. Recent advances in sensor technology and information processing afford a new flexibility in the design of waveforms for agile sensing. Sensors are now developed with the ability to dynamically choose their transmit or receive waveforms in order to optimize an objective cost function. This has exposed a new paradigm of significant performance improvements in active sensing: dynamic waveform adaptation to environment conditions, target structures, or information features. The manuscript provides a review of recent advances in waveform-agile sensing for target tracking applications. A dynamic waveform selection and configuration scheme is developed for two active sensors that track one or multiple mobile targets. A detailed description of two sequential Monte Carlo algorithms for agile tracking are presented, together with relevant Matlab code and simulation studies, to demonstrate the benefits of dynamic waveform adaptation. The work will be of interest not only to practitioners of radar and sonar, but also other applications where waveforms can be dynamically designed, such as communications and biosensing.

This book was released on 2012. Integrated Waveform-agile Multi-modal Track-before-detect Algorithms for Tracking Low Observable Targets available in PDF, EPUB and Kindle. In this thesis, an integrated waveform-agile multi-modal tracking-beforedetect sensing system is investigated and the performance is evaluated using an experimental platform. The sensing system of adapting asymmetric multi-modal sensing operation platforms using radio frequency (RF) radar and electro-optical (EO) sensors allows for integration of complementary information from different sensors. However, there are many challenges to overcome, including tracking low signal-to-noise ratio (SNR) targets, waveform configurations that can optimize tracking performance and statistically dependent measurements. Address some of these challenges, a particle filter (PF) based recursive waveformagile track-before-detect (TBD) algorithm is developed to avoid information loss caused by conventional detection under low SNR environments. Furthermore, a waveform-agile selection technique is integrated into the PF-TBD to allow for adaptive waveform configurations. The embedded exponential family (EEF) approach is used to approximate distributions of parameters of dependent RF and EO measurements and to further improve target detection rate and tracking performance. The performance of the integrated algorithm is evaluated using real data from three experimental scenarios.
