摘要

PROBLEM TO BE SOLVED: To improve measurement accuracy of the Doppler velocity of a target.;SOLUTION: A target speed measuring device 100 calculates the Doppler velocity of a target on the basis of a complex received signal in which a transmission signal transmitted at a predetermined repetition period via a radar antenna 30 is reflected on the target and received. The target speed measuring device 100 calculates the Doppler velocity of the target by performing the extended discrete Fourier transform (DFT) to the complex received signal in a range including an area where velocity return based on the predetermined repetition period occurs.;COPYRIGHT: (C)2013,JPO&INPIT
