In this paper, the problem of low probability of
identification (LPID) improvement for radar network
systems is investigated. Firstly, the security information is
derived to evaluate the LPID performance for radar network.
Then, without any prior knowledge o f hostile intercept
receiver, a novel fuzzy chance-constrained programming
(FCCP) based security information optimization
scheme is presented to achieve enhanced LPID performance
in radar network systems, which focuses on minimizing
the achievable mutual information (MI) at interceptor,
while the attainable MI outage probability at radar network
is enforced to be greater than a specified confidence
level. Regarding to the complexity and uncertainty of electromagnetic
environment in the modern battlefield, the
trapezoidal fuzzy number is used to describe the threshold
of achievable Ml at radar netw’ork based on the credibility
theory. Finally, the FCCP model is transformed to a crisp
equivalent form with the property of trapezoidal fuzzy
number. Numerical simulation results demonstrating the
performance of the proposed strategy are provided.
