PROBLEM TO BE SOLVED: To prevent degradations in the side-lobe characteristics and in performances of detecting results of Doppler estimation and to detect all the targets, even if each of frequency regions where the positive and the negative are reversed contains an appropriate frequency component with reflection wave signals reflected by different targets.SOLUTION: A rader system 100 includes: a correlator 111 obtaining a correlation value between a received pulse signal and a sent pulse signal; an IQ error estimation section 112 estimating an error of an I component and an error of a Q component of the received pulse signal based on the correlation value; a correction parameter calculation section 113 calculating a correction parameter for correcting the error of the I component and the error of the Q component; and a RXIQ error correcting section 109 correcting the errors of the I component and the Q component based on the correction parameter.SELECTED DRAWING: Figure 1 |
