Patent ID: 7352320

Claim:
An FM-CW radar comprising: a transmitting section operable to transmit a continuous wave frequency-modulated with a triangular wave; a mixing section operable to mix the continuous wave transmitted and a reflected wave of the continuous wave, which is reflected from a target, to generate a beat wave; an A/D conversion section operable to A/D convert the beat wave into digital data; a storage unit including a first storage section and a second storage section, each of the first storage section and the second storage section being operable to store the digital data; a signal processing section operable to process the digital data stored in the first storage section and the second storage section; and a control section operable to switch a storage section storing the digital data A/D converted by the A/D conversion section between the first storage section and the second storage section in synchronization with switching between up and down of the triangular wave, wherein the control section is operable to switch a storage section which stores the digital data processed by the signal processing section to a storage section which is different from the storage section storing the digital data A/D converted by the A/D conversion section in synchronization with the switching between up and down of the triangular wave.
