The strongest signals leaking off our planet are radar transmissions,not television or radio. The most powerful radars, such as the onemounted on the Arecibo telescope (used to study the ionosphere andmap asteroids) could be detected with a similarly sized antenna at adistance of nearly 1,000 light-years.

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.

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.

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.
