TABLE OF CONTENTS In this chapter we summarised the basic tools for considering problems of signal processing from an engineering viewpoint. After the introduction of basic statistics we discussed the likelihood ratio test for deriving optimal processing rules for signal or target detection. Some important examples have been treated.
The parameter estimation has to follow target detection in most applications. The basic procedure has been given, together with the determination of the achievable accuracy for the parameter estimate given by the Cram r-Rao bound.
Signal estimation is also sometimes required. The basic procedure has been described.
A general problem in radar is interference suppression. A processing rule derived from the likehood ratio test has been used for discussion of the general mechanism.
