Forecast and Elimination of Radiation-Field Zero-Zone on TACAN Guidance Station

The radiation-field zero-zone on TACAN guidance station has the deep-going influence on the performance of TACAN system. It is important to analyze and forecast the zero-zone station position in order to ensure the main route and approach route. The paper analyses the forming process of radiation-field zero-zone, and puts forward the methods of the forecasting zero-zone station, the effective compensatory measure which has reduced the influence on zero-zone is given. It is of momentous directing significance to select the field of TACAN guidance station and to set up the TACAN system.
