1. A radar device comprising:
a signal generation unit being a circuit configured to generate a signal as an original signal;
at least one pseudo-random number generation unit, each of the at least one pseudo-random number generation unit being a circuit, configured to generate a pseudo-random number sequence formed of a pseudo-random number of one bit or more;
a true random number generation unit being a circuit configured to generate a true random number sequence formed of a true random number of one bit or more;
at least one modulation code synthesizing unit, each of the at least one modulation code synthesizing unit being a circuit, configured to generate a modulation code sequence for use in modulating a signal phase by synthesizing the pseudo-random number sequence and the true random number sequence, the modulation code sequence including a component derived from the true random number sequence;
at least one phase modulation unit, each of the at least one phase modulation unit being a circuit, configured to generate a transmission signal by modulating a phase of the original signal by using the modulation code sequence, wherein
the modulation code sequence is a modulation code sequence in which the component derived from the true random number sequence disappears by synthesizing two modulation code sequences.
