Considering feature of shape of burden surface procedure to the distributed radar sensors

distributing principle of radar sensors and comprehensive evaluation function of optimized layout are proposed

which is constrained optimal issue within the circular definition domain.A novel method called multiplier penalty function based on loop domain search is put forward to deal with such an optimal issue.An example of optimal layout of radars in a steel plant is discussed

and the result indicates that compared with initial manual layout

the evaluation function value is increased by 1.5 %

which verifies that this method is effective in optimizing layout of blast furnace radar sensors.
