Abstract-- In recent work we introduced the notion of diversity
in distributed radar systems and we evaluated the diversity order
of fully distributed networks. Our long-term goal is to analyze the
trade-off between distributed detection and detection using co-
located antennas. In this paper, we extend our earlier analysis
and we evaluate the diversity of joint detection for symmetric
noise-limited systems. The Neyman-Pearson (NP) statistic for
joint detection is shown to follow a Gamma distribution. We
prove that the diversity order of large networks is on the order of
