Abstract
An FM-CW radar includes a transmitting section, a mixing section, an A/D conversion section, a storage unit, and a signal processing section. The transmitting section transmits a continuous wave frequency-modulated with a triangular wave. The mixing section mixes the continuous wave transmitted and a reflected wave from a target, to generate a beat wave. The A/D conversion section A/D converts the beat wave into digital data. The storage unit includes a first storage section and a second storage section. The signal processing section reads data from the first storage section to process the read data. The A/D conversion section writes the digital data into the second storage section. The control section switches the first storage section and the second storage section alternately in synchronous with switching between up and down of the triangular wave.
