1. A radar device comprising:
a plurality of transmission radars to transmit transmission radio-frequency signals by performing phase modulation on pulse signals with a same transmission frequency, using amounts of phase modulation, the transmission radio-frequency signals being the phase-modulated pulse signals, and the amounts of phase modulation varying between hit numbers;
a reception radar to receive, as a reception radio-frequency signal, each of the transmission radio-frequency signals having been transmitted from each of the plurality of transmission radars, and then reflected by a target; and
a signal processor to detect a candidate for the target on a basis of the reception radio-frequency signal received by the reception radar, wherein
each of the plurality of transmission radars uses, as a corresponding one of the amounts of phase modulation (Δϕ(nTX,h)):
a value determined from either one of a positive integer value (P(nTX)) that is less than or equal to a result of division and a value of 0, where nTX is an identifier;
a hit number (h); and
a number of hits (H) of a corresponding one of the transmission radio-frequency, signals,

the result of division being obtained by dividing the number of hits (H) by a number of the plurality of transmission radars (NTX), the value referring to different amounts of the phase modulation satisfying a formula below:, Δφ
