基于干扰保护比的同频航向信标台最小保护间距计算
Interference Protection Ratio Based Computation of Minimum Cochannel Localizer Station Protection Distance
摘要
Abstract
A numerical computation method for minimum protection distance is proposed for cochannel lo-calizer(LOC) stations under several typical scenarios. For this proposed method,the function of required protection distance is fitted based on the distance curves between LOC stations, and the space distance curves corresponding to these scenarios are obtained from the geometrical function. The minimum LOC co-channel distance is determined based on the relationship between the required protection distance and the space distance. Compared with the relatively conservative protection distance provided by the Federal Avia-tion Administration( FAA) regulation,the proposed method can obtain more accurate and smaller LOC co-channel distances under the fundamental premise of safety. Therefore,the frequency utilization efficiency of LOC systems can be improved.关键词
