Abstract: Joint probability of target detection in a system of multiple radar sets is studied.Several models of optimum deployment in circle, line, sector and multi-line, respectively, have been built.Optimum models of circle, line and sector deployment can be obtained using methods of exhaustive enumeration, golden section, or coordinate alternation. For multi-line arrays, if the number of radars is not too large, the problem can be solved using a combination of exhaustive enumeration and coordinate alternation.When the number of radars is large, a combination of genetic algorithm and the coordinate alternation method should be used.

Key words: target detection probability, Monte Carlo method, genetic algorithm, coordinate alternation, golden section method
