MULTI-FREQUENCY CHIRP SIGNAL GENERATOR

摘要

The present invention relates to a simultaneous multi-frequency chirp signal generator and, more specifically, to a simultaneous multi-frequency chirp signal generator which includes: an integrated circuit unit (1) which generates a chirp signal, as configured with multiple direct digital frequency synthesizers (DDSs); a multiplexing unit (2) which multiplexes a signal output from the integrated circuit unit (1); a D/A converting unit (3) which converts the signal multiplexed by the multiplexing unit (2) into an analog signal; and a filter unit (4) which is configured with a filter allowing only a signal in a desired band to form the received signal into a desired frequency spectrum.
