8:00AM – 9:00AM Registration & Coffee

9:00AM – 11:30AM Newly Emerging Radar Technology : Cognitive Radar: The Knowledge-Aided Fully Adaptive Approach

This workshop will provide an in-depth and comprehensive overview of the emerging field of cognitive radar (CR). Particular emphasis will be placed on the first specific real-time cognitive radar architecture based on extensive knowledge-aided (KA) processing, and full joint transmitreceive adaptivity. Applications considered include enhancing detection and target ID in complex interference and clutter environments, as well as the emerging problem of RF spectrum management.

What will be covered?

  • Optimal multi-input, multi-output (MIMO) radar design
  • Advanced real-time knowledge-aided (KA) processing
  • Cognitive radar architecture based on KA processing and full MIMO adaptivity
  • Applications spanning a number of radar areas.

How you will benefit:

  • Keep up with the latest developments in this newly emerging radar technology
  • Obtain a working understanding of fundamental cognitive radar architecture
  • Learn what current radar challenges can be addressed with cognitive radar
  • Understand what opportunities exist for future developments and applications

11:30AM – 12:30PM Lunch

12:30PM – 2:30PM Approaches For Minimizing Spectral Problems: Power Amplifier Circuit And Waveform Optimization For Reduced Spectral Spreading In Radar Transmitters

Increasingly stringent spectral requirements on radar systems throughout the world have created a spectrum crisis for radar designers. Demand for spectrum by expanding broadband wireless applications providing services such as increased data rates, web, real-time video, and other applications continue to lower the amount of spectrum allocated to radar by regulatory agencies in the United States and around the world. New and innovative power amplifier and waveform design practices are needed to reduce the spectral spreading caused by radar power amplifiers.

What will be covered?

  • Sources of nonlinearity causing spectral spreading in power amplifiers
  • Methods for improving efficiency and linearity in power amplifier design
  • Nonlinear calculus and “X-parameters” for characterization of system nonlinearities
  • Using nonlinear calculus and bench-top measurements to optimize both waveform and circuit design

How you will benefit:

  • Gain holistic (waveform and circuit design) perspective on causes of spectral problems
  • Acquire a familiarity with state-of-the-art principles of linear and efficient power amplifier design
  • Understand methods for characterizing nonlinear frequencyconversion behavior in systems, such as X-parameters
  • Discover developing research in approaches for minimizing spectral problems in radar transmitters

2:45PM – 4:45PM Bi-Static Radar Advances: Radio Aurora Explorer: Resolving The K-Space Of Ionospheric Turbulence Through A Ground-To-Space Bi-Static Radar

Ionospheric turbulence measurements in the high latitudes have not been possible due to monostatic radar scattering difficulties associated with a near-vertical geomagnetic field. As the first NSF-funded CubeSat mission, RAX, in coordination with five UHF incoherent scatter radars on the ground, enables a unique bi-static remote sensing capability providing unprecedented angular and spatial resolution measurements of natural and artificial ionospheric irregularities, while simultaneously measuring electrodynamic forcing by an ISR.

What will be covered?

  • Implications of ionospheric turbulence for space weather
  • Bi-static ground-to-space radar geometry formed by a LEO satellite
  • UHF payload radar receiver and data acquisition on a CubeSat platform
  • TX-RX Synchronization

How you will benefit:

  • Explore how alternative RAX measurements may benefit others
  • Learn about space weather implications for the space-based radar community
  • Understand challenges encountered by existing space-based radar missions
  • Discover new ideas and collaborations for future projects
