description An interference suppression method and a detection apparatus are provided. A radar determines a group of optimized phases of a transmit signal at a transmit end, and modulates an initial phase of the transmit signal into an optimized phase. The optimized phase is different from an initial phase of an interference signal, so that the interference signal cannot be accumulated when the radar performs coherent accumulation on an echo signal of the transmit signal at a receive end. This can suppress a ghost target caused by synchronization between the radar transmit signal and the interference signal.
