resented in this paper. Based on the measured

radar cross section (RCS) of interested targets and

the coverage diagrams of the different radars in a

radar network, the approach can be used to solve

the problem of how optimally to locate the radars

to achieve a satisfactory surveillance area and some

highly concerned areas (i.e., core ureas) inside.

Several factors have been taken into account in this

approach, such as local terrain around radar, manmade

interference, flying direction of target, etc.

Simple examples are discussed for illustrative

purpose.
