在新机场的选址过程中,常常遇到预选场址附近已设有地面视距微波站(以下简称微波站)的情况。由于这些微波站先于机场投入使用,微波通信电路已形成固定工作模式,因此在一定的空间和地面位置上制约着机场的选址。若预选场址地理范围较大,尚可以避开微波电路选址;而一旦受地理环境和其他条件限制,预选场址无法避开微波电路,则不可避免的要发生机场场址与微波电路的矛 In the process of siting a new airport, it is often the case that a ground-view microwave station (hereinafter referred to as a microwave station) already provided near the pre-selected site has been set up. Since these microwave stations are put into operation before the airport, the microwave communication circuit has formed a fixed working mode, so the location of the airport is restricted in certain space and ground position. If the pre-selected site geographically large, can still avoid the microwave circuit site selection; and once by the geographical environment and other conditions, the pre-selected site can not avoid the microwave circuit, it is inevitable to the airport site and the microwave circuit spear
