PURPOSE:To obtain the delivery signal by synthesizing the phase at the micorwave band with a simple constitution, through the control of the oscillation frequency of the shift oscillator at one side with the phase difference of two input reception wave. CONSTITUTION:The first and second output can be obtained by performing frequency shift of the reception waves incoming to the reception antennas 11 and 21. Further, the frequency of the shift oscillators 15 and 25 to shift the first and second reception frequency is controlled with the signal obtained from the phase comparison 16 for these outputs. Thus, the reception frequency signal of the first and second respectively shifted is phase-synthesized in the micro-wave band with a simple constitution, allowing to obtain the transmission signal. |
