PULSE COMPRESSION RADAR

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) 1 includes an antenna 10 configured to externally transmit a transmission signal transmitted by a power amplifier 16 and receive a reflection signal caused thereby as a reception signal. The radar apparatus 1 includes a reception circuit 41 configured to propagate this reception signal to a radar image creating module 26. The radar apparatus 1 corrects beforehand, by utilizing the transmission signal (feedback signal) transmitted from the power amplifier 16, a transmission signal to be inputted into the power amplifier 16 so as to cancel distortion of the transmission signal caused by amplification effect of the power amplifier 16. Further, a circuit where the reception signal passes and a circuit where the feedback signal passes share a part of each other.
