Title:
PULSE COMPRESSION RADAR
Document Type and Number:
WIPO Patent Application WO/2014/045928
Kind Code:
A1
Abstract:
[Problem] To provide, for a radar device which performs predistortion processing, a configuration capable of immediately sending a transmission signal without distortion even if power is lost.
[Solution] A radar device (1) (pulse compression radar) calculates a correction coefficient on the basis of a transmission signal before distortion occurs and a transmission signal output by a power amp (16) (feedback signal). The radar device (1) corrects a transmission signal output by an ideal transmission signal storage unit (33) using the correction coefficient and taking into consideration the distortion generated during amplification by the power amp. The radar device (1) is provided with a non-volatile memory (38) for storing the calculated correction coefficient as a backup.
