In this paper, the non-synchronized integration of multiple frequency-modulated continuous-wave (FMCW) radars is presented. A phase error deduction method on different non-synchronized radars using trust-region-reflective least squares algorithm is introduced. Better angle of arrival (AoA) estimation, better angular resolution and better side lobes deduction are realized in experimental result. Therefore, integrating multiple independent radar systems to emulate a large aperture is achieved.
