Patent Images
1. A radar transceiver that transmits an upbeat signal and a downbeat signal, simultaneously, and receives the upbeat signal and the downbeat signal to detect a target object, the radar transceiver comprising:
- a transmission-signal forming section that forms the upbeat signal and the downbeat signal from a carrier signal and a chirp signal, using an image rejection circuit;
a transmission section that simultaneously transmits the upbeat signal and the downbeat signal formed by the transmission-signal forming section;
a reception section that receives a reflection signal generated when the transmitted upbeat and downbeat signals are reflected from the target object; and
a received-signal processing section that separates, using an image rejection circuit, the reflection signal received by the reception section into a reflection signal based on the upbeat signal and a reflection signal based on the downbeat signal.

Abstract
A radar transceiver (100) includes: a transmission-signal forming section (110) that forms an upbeat signal and a downbeat signal from a carrier signal and a chirp signal, using an image rejection circuit; and a received-signal processing section (120) that separates a reflection signal received via a reception antenna (105) into a reflection signal based on the upbeat signal and a reflection signal based on the downbeat signal, using an image rejection circuit.
