In this chapter we compare three different kinds of radar systems. The first is the classic MIMO case characterized by antennas located far from each other so that they see independent backscatter from a complex target. The second case considers the same radar configuration but this time coherent summation is performed at each receiver in an attempt to maximize the signal-to-noise ratio. We term this netted radar. In the third case we consider an examination of the performance when frequency diversity is substituted for the angle diversity of the first case. This potentially provides a method of achieving the effects of MIMO from a non-distributed aperture. In all three cases the total power available is kept constant such that fair comparisons may be made. Finally we discuss the importance of the role of the target scattering behavior and examine alternative models to that used here. The effect of multipath is also included in the analysis.
