Abstract

A radar apparatus and a radar detecting method are provided. The radar apparatus includes a transmitting circuit, a transmitting antenna system and a receiving antenna system. The transmitting circuit is used to generate two transmission signals having different bandwidths. The transmitting antenna system is used to transmit these two transmission signals. The receiving antenna system is used to receive two reflected signals having different bandwidths. The two reflected signals are generated by the reflection of the two transmission signals by an external object. One of the two transmission signals and one of the two reflected signals are used for a first detection mode, and the other one of the two transmission signals and the other one of the two reflected signals are used for a second detection mode. The detection power of the first detection mode is greater than the detection power of the second detection mode.
