A radar transmission unit (Tx) transmits high frequency radar transmission signals from a transmission antenna (Tx_ant1). Each of antenna system processing units (D1) receives reflected wave signals by means of a reception antenna (Rx_ant1), said reflected wave signals being the radar transmission signals reflected by an object, and each of the antenna system processing units calculates correlation between the reflected wave signals and the radar transmission signals. On the basis of outputs of the (Tp+1) (Tp is an integer) number of antenna system processing units (D1), an object detection processing unit (10) detects whether there is an object or not using amplitude differences between an amplitude of an output of the (Tp+1) th antenna system processing unit (D1) and respective amplitudes of outputs of the first to the Tp th antenna system processing units (D1). |
