  4. The course  Style: /Graduate Course with Active Participation/

  5. Introduction  Let’s start with a radar example!

  6. Introduction> Radar Example  QUIZ

  7. Introduction> Radar Example You can actually explain it in ten seconds!

  8. Introduction> Radar Example Applications in Transportation, Defense, Medical Imaging, Life Sciences, Weather Prediction, Tracking & Localization

  9. Introduction> Radar Example The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years. - Seth Shostak, SETI

  10. Introduction> Estimation  Traditionally discussed in STATISTICS.  Estimation in Signal Processing: Digital Computers ADC/DAC (Sampling) Signal/Information Processing

  11. Introduction> Estimation  The primary focus is on obtaining optimal estimation algorithms that may be implemented on a digital computer.  We will work on digital signals/datasets which are typically samples of a continuous-time waveform.

  12. Introduction> Estimation  Estimation theory deals with estimating the values of parameters based on measured/empirical data that has a random component.  The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data.  An estimator attempts to approximate the unknown parameters using the measurements.

  13. Introduction> Detection  Detection theory is a means to quantify the ability to discern between information-bearing patterns and random patterns (called noise).  Typically boils down to a “hypothesis test” problem.

  14. Introduction> Modeling for Detection and Estimation

  15. Introduction> Estimation or Detection – which comes first?
