  The Search and Rescue Network (SAR) is a kind of emergency network that
pursuit people in need or imminent danger. This paper aims using a priori
optimization to demonstrate the optimal assignment of HFDF receivers to the
Generalized Search and Rescue (GSAR) network, which is independent of the
weighting of the transmitter areas. The mathematical model seeks two
objectives, the first one is maximizing the expected number of LOBs for HFDF
receivers. The second is providing a fair share number of HFDF receivers
allowed to cover the frequency. The result shown the efficiency of presented
model ran by CPLEX toolbox of MATLAB 2020 software.
