Abstract: A pulse radar apparatus is disclosed. The pulse radar apparatus includes a pulse generation unit, a receiver unit, a synchronization unit, and a switch unit. The pulse generation unit generates a pulse based on a transmission trigger signal having a transmission pulse repetition period, and sends the pulse to a target via a transmission antenna. The synchronization unit generates the transmission trigger signal using an external reference clock, provides the transmission trigger signal to the pulse generation unit, and generates a plurality of clock signals having a time delay with respect to the transmission pulse trigger signal using the external reference clock. The switch unit selects any one clock signal from the plurality of clock signals in response to an external selection signal, and provides the selected clock signal to a receiver unit which utilizes a sampler with provided sampling clocks.
