2. Statistical modeling of the problem
The methodology presented in the first part [ , § 2] is applicable as soon as the probability density of the observation can be described. This presupposes the ability to represent the signal by a finite set of numbers (sampling), and then to establish a relationship between the physical parameters and the statistical parameters.
2.1 Antenna signal representation
The observation corresponds primarily to the signals received by the antenna's sensors over a finite period of time [0, T ] :
