A detection apparatus, a radar, and a terminal are provided, and relate to the field of sensor technologies. The detection apparatus includes: a transceiver (101), configured to transmit a first signal (E1), where the first signal (E1) includes a double-sideband signal, and configured to receive a second signal (E2), where the second signal (E2) is a reflected signal corresponding to the first signal (E1); a coupler (102), configured to: receive a local oscillation signal (ELO) and the second signal (E2), and output at least three output signals (C1, C2, and C3), where the local oscillation signal (ELO) and the first signal (E1) are obtained by splitting a third signal (E3) from a modulator (104); and a processor (103), configured to obtain a detection result based on the at least three output signals (C1, C2, and C3). Hardware costs of the detection apparatus can be reduced. The detection apparatus is applied to a radar system, and the radar system is further applied to the terminal, so that hardware costs of the radar system and the terminal can be reduced while detection precision is ensured.
