摘要

An active phased array transmitter includes: a transmission frequency signal source that generates a transmission frequency signal; a modulator that modulates the transmission frequency signal based on transmission data and outputs the modulated transmission signal; a plurality of transmitters that change the phase and intensity of the modulated transmission signal; a transmission phased array antenna including a plurality of transmission antennas; a local transmission frequency signal source that generates a local transmission frequency signal; a first mixer that generates a first intermediate frequency transmission signal from a received signal of the radio waves output from the transmission antennas and the local transmission frequency signal; a second mixer that generates a second intermediate frequency transmission signal from the modulated transmission signal and the local transmission frequency signal; a transmission correlation processing circuitry that detects a transmission correlation relationship; and a transmission relative relationship detector that detects, from the transmission correlation relationship.
