SIGNAL PROCESSING APPARATUS AND METHOD THEREOF

摘要

The present invention relates to a signal processing system, which removes an electromagnetic interference signal possibly transmitted from other communications device, radar and all kinds of electronic equipment using a radar reception signal, and a method for the same. The signal processing system according to the invention comprises: a native signal generator which receives a parameter value set by a user and generates a native signal based on the received parameter value; an interference signal generation and application unit which generates at least one of narrowband interference signals, multiple narrowband interference signals, and broadband interference signals, and mixes the generated interference signal with the native signal to generate a reception signal including the interference signal; an interference signal removing unit which removes the interference signal included in the reception signal through either a notch filter with a predefined threshold value or a least mean square (LMS) adaptive filter that is an LMS filter set with a weight; and a signal processing unit, which performs the predefined signal process for the reception signal with the interference signal removed and displays an image generated according to the result of the signal process and the frequency spectrum of the reception signal from which the interference signal is removed.
