The oscillation phase control unit and its control manner null of oscillation device

摘要

PPROBLEM TO BE SOLVED: To easily control directivity of a beam of an oscillator array constituted of a plurality of oscillators. PSOLUTION: An oscillation array oscillation phase control apparatus is constituted of an oscillator array configured, by electromagnetically coupling in an array shape a plurality of oscillation elements which oscillate at the same predetermined oscillation frequency; and a synchronization signal injection means for applying to an oscillation element 1A that is positioned at one end of the oscillator array, a synchronization signal of a frequency that is out of frequency range wherein the oscillator array is synchronized, and is higher than the oscillation frequency, and applying to an oscillation element 1B, that is positioned at another end of the oscillator array, a synchronizing signal of a frequency which is out of the frequency range wherein the oscillator array is synchronized and is lower than the oscillation frequency. A plurality of oscillation elements 1, excluding the oscillation elements 1A, 1B, positioned at the ends of the oscillator array at least, are set valid and output is obtained.
