    摘要： A radar device includes transmission signal generation circuitry that generates one or more transmission signals, a transmission amplifier that amplifies a power level of the one or more transmission signals, a transmission gain controller that adjusts a gain of the transmission amplifier, transmission antenna circuitry that converts each of the one or more amplified transmission signals into each of one or more radio signals and transmit the one or more radio signals to a measurement target space, reception antenna circuitry that receives the one or more radio signals from the measurement target space, and one or more receivers that detect a power level of a transmission/reception leakage signal using the one or more received radio signals. The transmission gain controller adjusts the gain of the transmission amplifier in accordance with a result of comparison between the detected power level and a power level of a transmission/reception leakage signal measured in advance.

    摘要： A wireless communication device includes a baseband variable gain amplifier that amplifies a transmission baseband signal, a local variable gain amplifier that amplifies a local signal, a frequency-conversion circuit that mixes the amplified transmission baseband signal and the amplified local signal to carry out a frequency conversion into a transmission high-frequency signal, a first detector that detects a power of the transmission high-frequency signal, and a controller that controls at least one of a gain of the transmission baseband variable gain amplifier and a gain of the local variable gain amplifier on the basis of the detected power of the transmission high-frequency signal so that a power of the transmission high-frequency signal to be detected takes a predetermined value.

    摘要： In signal processing of the present disclosure, an abnormal correction value as a correction value for correcting a quadrature error that occurs in quadrature modulation is output in malfunction determining processing, and a normal correction value as the correction value is output in calibration processing. The presence or absence of malfunction in the signal processing is determined on the basis of the levels of carrier leak and image leak of the quadrature modulated signal.
