摘要: A microwave transmission system suitable for use as an aircraft landing consists of a linear array radiators each which radiates the same carrier signal. The signal is modulated with triangular frequency constant amplitude modulation; application modulation being progressively delayed different in array. This produces radiated pattern consisting spokes; spoke having unique and direction. By noting received can determine its angular position relative to transmitter.
