为使防区内多探测源的探测效能发挥最大，并有利于探测到低空突防目标，必须满足预警网探测的连续性和严密性。文中在假定的预警区域内给出了一条最优的突防航迹，同时提出了根据突防航迹和各类探测源的性能差异进行多探测源优化组网的方案——网格GT搜索算法。结果表明，该布站方案能有效地探测超低空突防的飞行器。

To achieve the maximal operation effectiveness of radar sensor in the defence area, and to detect the low altitude object, it is necessary to meet netting strictness and continuity of detection. Gridded GT search is an approach of radar netting. A method is proposed to solve the problem of how to locate optimally the different radars in a radar network to detect the aircraft of exceedingly low altitude. For optimal radar positions of all kinds of radars and penetration route of low altitude objects, this approach proves to be effective.
