Clutter-Free Localization by Harmonic Radar at 60/120 GHz

Sprache: Englisch

Accurate range measurements near other reflectors, known as clutter, can be challenging for conventional FMCW radars, especially when the target of interest has a small radar cross-section. Even if the distance between different reflectors is large enough, it is not always clear which reflector is the target of interest in cluttered radar scenarios. These challenges can be addressed by placing a harmonic reflector, the tag, on the target of interest. The tag, which consists of antennas and a nonlinear device, responds with an impulse response at a harmonic frequency that is distinct from the passive environment with its linear characteristics. With a receiver also operating at the appropriate harmonic frequency, only the tag's response is converted to the intermediate frequency.
