In this letter, we analyze the performance trade-off in distributed
integrated sensing and communication (ISAC) networks. Specifically, with the
aid of stochastic geometry theory, we derive the probability of detection of
that of the coverage given user number. Based on the analytical derivations, we
provide a quantitative description of the performance limits and the
performance trade-off between sensing and communication in a distributed ISAC
network under the given transmit power and bandwidth budget. Extensive
simulations are conducted and the numerical results validate the accuracy of
our derivations
