An onboard radar apparatus includes a transmission wave generating unit configured to generate a transmission wave, a vertically polarized wave transmitting antenna configured to vertically polarize and transmit the transmission wave, a horizontally polarized wave transmitting antenna configured to horizontally polarize and transmit the transmission wave, a receiving antenna configured to receive a reflection wave, a switch control unit configured to perform a switching between the vertically polarized wave transmitting antenna and the horizontally polarized wave transmitting antenna, and a receiving unit configured to receive one of the reflection waves based on receiving levels of the reflection waves, which have been received by the receiving antenna before and after the switching is performed by the switch control unit.
