摘要： A radar apparatus configured to prevent a harmonic generated by a limiter from being transmitted outside is provided. The radar apparatus includes a harmonic processor between a circulator and a limiter. The harmonic processor includes harmonic processing stubs, and a compensation stub. The harmonic processing stubs attenuate the harmonic which is generated when the limiter attenuates a transmission signal passed through the circulator. The compensation stub cancels a change of a susceptance caused by disposing the harmonic processing stubs.

摘要： A pulse compression radar for performing pre-distortion is provided, which has a configuration simplified in circuit structure. A radar apparatus (pulse compression radar) includes an antenna configured to externally transmit a transmission signal transmitted by a power amplifier and receive a reflection signal caused thereby as a reception signal. The radar apparatus includes a reception circuit configured to propagate this reception signal to a radar image creating module. The radar apparatus corrects beforehand, by utilizing the transmission signal (feedback signal) transmitted from the power amplifier, a transmission signal to be inputted into the power amplifier so as to cancel distortion of the transmission signal caused by amplification effect of the power amplifier. Further, a circuit where the reception signal passes and a circuit where the feedback signal passes share a part of each other.
