Measurements of the properties of bistatic radar clutter have shown that amplitude statistics of bistatic clutter depend on the bistatic geometry, such that the distribution of the bistatic clutter may be shorter-tailed (less `spiky') than the equivalent monostatic clutter. At the same time, the bistatic signature of targets may be significantly different from their monostatic signatures. Clutter Diversity may be defined as: `understanding and quantifying these effects, and finding out how best to exploit them', and offers a new degree of freedom in the design of radar systems. This chapter reviews the properties of clutter and of targets as a function of bistatic geometry, and explores the effects of detection performance.
