A non-transitory computer-readable medium stores machine instructions that cause a processor to obtain a range-sample-antenna data cube for a received radar signal comprising reflections of a plurality of interleaved chirp sequences. The processor generates, for each chirp sequence, a Hankel matrix based on subset of range bins for the particular chirp sequence, and generates a block Hankel matrix based on the Hankel matrices for the plurality of interleaved chirp sequences. The processor performs truncated singular value decomposition to estimate subspaces, and object detection to identify selection matrices. The processor calculates least-squares approximations for the selection matrices and the block Hankel matrix to obtain, for each chirp sequence, a first phase shift matrix θand a second set of phase shift matrices θ, l=2, . . . , L. The processor performs joint diagonalization and Doppler division multiplexing compensation on θand θ, l=2, . . . , L, then resolves ambiguities in determined velocities based on comparison of θand θ, l=2, . . . , L.
