A Precise and Accurate Indoor Localization System based on Sub-Harmonic FMCW Radar
2018 25th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2018This paper presents an accurate indoor localization system based on sub-harmonic frequency modulated continuous wave (FMCW) radar where a 24 GHz frequency divider-by-10 is used as an active reflector tag. Indoor positioning measurements are performed using least-mean-squares (LMS) algorithm.

In this letter, we present a direction-of-arrival (DOA) estimation algorithm named Harmonic Retrieval joint Multiple Regression (HRMR) for FMCW radar against unknown spatially colored noise. The HRMR algorithm focuses on the direct data domain. First, the target’s IF signal is resolved and reconstructed by the selected harmonic retrieval method.
