Abstract

A method for use in a radar device is described herein. In accordance some implementations, the method includes generating an RF oscillator signal which includes frequency-modulated chirps, amplitude-modulating the RF oscillator signal by a modulation signal, and transmitting the amplitude-modulated RF oscillator signal via at least one antenna. In some implementations, the method may further include receiving an RF signal that includes frequency-modulated chirp echo signals from a target object, down-converting the received RF signal into a base band using the RF oscillator signal for providing a base band signal, and processing the base band signal to detect information included in the modulation signal.
