Radar interference canceller and the radar interference removal method

摘要

PROBLEM TO BE SOLVED: To remove interference extending in a distance direction and resulting in frequency modulation.;SOLUTION: A radar interference removal apparatus, with respect to an input signal of each sweep obtained for each repetition frequency of a radar, acquires the instantaneous frequency of the input signal, calculates correlation between the instantaneous frequencies of the input signal corresponding to a focused sweep and a distance focused with a sweep following the focused sweep, determines the presence/absence of the correlation by the calculation result, and when it is determined that there is no correlation, removes the input signal.;COPYRIGHT: (C)2013,JPO&INPIT
