RADAR DEVICE |
| 摘要 |
A radar device is provided with: a transmitter that transmits a high-frequency radar transmission signal from a transmission antenna; a controller that controls execution or stopping of transmission of the radar transmission signal; a receiver that amplifies a thermal noise signal inputted from reception antenna by using an initial gain value and quantize the amplified thermal noise signal, while the transmission of the radar transmission signal is stopped; and a gain controller that adjusts the prescribed gain value to a gain value suitable for dithering of the thermal noise signal, based on the quantized thermal noise signal. |
