Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/074718
Kind Code:
A1
Abstract:
A radar device (100) comprises an antenna unit (22) that emits radar waves into a space, a high-frequency circuit (17) that receives, via the antenna unit (22), waves reflected from a target of the radar waves, and a baseband circuit (18) that converts a received signal outputted from the high-frequency circuit (17) into a baseband signal having a digital value. In the antenna unit (22), the high-frequency circuit (17), and the baseband circuit (18), a plurality of reception channels are configured. The baseband circuit (18) includes a baseband amplifier (20) that amplifies, for each of the reception channels, the received signal outputted from the high-frequency circuit and performs parallel addition, and an analog-digital converter (14) that converts an analog signal outputted from the baseband amplifier (20) into a digital value.
