Single Channel MMWave FMCW Radar for 2D Target Localization

TL;DR

This paper introduces a cost-effective 2D target localization technique using two FMCW radars at 79 GHz, employing bilateration and multi-target tracking to accurately map targets and eliminate ghost artifacts.

Contribution

The paper proposes a novel 2D localization method with a multi-radar setup and ghost target removal, demonstrated through real-world experiments.

Findings

Successful 2D mapping of targets using two FMCW radars

Effective ghost target removal with multi-target tracking

Validated approach with experimental data at 79 GHz

Abstract

In this paper, we present a 2D target localization method using two low cost and compact Mellimeter Wave Frequency Modulated Continuous Wave (MMW-FMCW) radars. To create a 2D map we exploit the bilateration method followed by a multi-target tracking block to remove the ghost targets. Finally, we present experimental results based on the data gathered from two FMCW radars operating at $\rm 79 \;GHz$.
