CORRELATED RECEPTION PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a correlated reception processing device capable of suppressing sidelobes of a desired signal and other signals, even if multiple kinds of signals are propagated in space.

SOLUTION: A suppression weight calculating module 2233 calculates a suppression weight matrix WB to suppress a signal SB to zero and a suppression weight matrix WC to suppress a signal SC to zero. An unwanted signal suppression module 2232 suppresses the signals SB and SC in an input signal matrix X by multiplying a signal after FFT by the suppression weight matrices WB and WC. A sidelobe-free coefficient calculating module 2234 calculates an autocorrelated sidelobe-free coefficient matrix to suppress the sidelobes of a signal SA by considering the state of the input signal matrix X multiplied by the suppression weight matrices WB and WC. A sidelobe suppression module 2236 suppresses the sidelobes of the signal SA by multiplying the signal from the unwanted signal suppression module 2232 by the sidelobe-free coefficient matrix.
