In this chapter, we address the problem of data representation and its impact on human motion classification using radar. In examining the motion classifier performance, it has become apparent that some human motion articulations are more distinguish-able in some data domain representations than others. The potential effect of data representation on motion classification performance calls for devising proper strategies and new approaches of how to best manipulate or preprocess the data for the sake of achieving most desirable results. We discuss domain integration and suit-ability using a single range-Doppler radar sensor. No assumptions are made regarding the received radar backscattering data adhering to any specific models or signal structure.
