Abstract: PURPOSE: A self-tuning type phase difference detector is provided to measure correctly a phase difference of an incident signal by using a self-generation signal without tuning a frequency of the incident signal. CONSTITUTION: A self-tuning type phase difference detector comprises a first high frequency signal distribution portion(404), a second high frequency signal distribution portion(414), an oscillator(220), a tuning signal generation portion(230), a first intermediate frequency generation signal output portion(240), a second intermediate frequency generation signal output portion(250), and a phase determination portion(260). The first high frequency signal distribution portion distributes a first high frequency signal to two paths. The second high frequency signal distribution portion distributes a second high frequency signal to two paths. The oscillator generates a fixed oscillating frequency. The tuning signal generation portion tunes a second output signal of the first high frequency signal distribution portion to the output signal of the oscillator. The first intermediate frequency generation signal output portion outputs a first intermediate frequency signal by tuning a first output signal of the first high frequency signal distribution portion to a tuning signal of the tuning signal generation portion. The second intermediate frequency generation signal output portion outputs a second intermediate frequency signal by tuning a first output signal of the second high frequency signal distribution portion to the tuning signal of the tuning signal generation portion. The phase determination portion determines a phase difference.

Abstract: PURPOSE: An apparatus is provided to prevent the vagueness of a direction measurement owing to generation of the same phase in a predetermined interval, by arranging a plurality of antennas in the same interval. CONSTITUTION: An apparatus for comparing a phase and finding a direction comprises a plurality of antennas which are circularly arranged in the same interval. A phase center compensating part adjusts a sector and a phase value of each frequency to '0'. An amplitude direction calculating part outputs an amplitude direction signal. A period judging part receives the phase value from the phase center compensating part, and directs a period, in which the vagueness exists, by use of a sector and a frequency. A phase direction compensating part receives the phase value from the phase center compensating part and the period judgment directing signal, and compensates a phase direction by use of the sector and the frequency.
