1. A method for generating a jamming signal performed by an apparatus for generating the jamming signal, the method comprising:
obtaining at least one codeword matched previously to binary bits by converting the binary bits of a first communication signal to be transmitted to the at least one codeword;
generating a second communication signal by superimposing a first conversion signal being obtained by converting the first communication signal to an up-chirp signal and a second conversion signal being obtained by converting the first communication signal to a down-chirp signal; and
generating a pseudo jamming signal based on the second communication signal and the codeword.
