AB  - In this paper, we introduce a Reduced-Dimension Multiple-Signal Classification 
      (RD-MUSIC) technique via Higher-Order Orthogonal Iteration (HOOI), which 
      facilitates the estimation of the target range and angle for Frequency-Diverse 
      Array Multiple-Input-Multiple-Output (FDA-MIMO) radars in the unfolded coprime 
      array with unfolded coprime frequency offsets (UCA-UCFO) structure. The received 
      signal undergoes tensor decomposition by the HOOI algorithm to get the core and 
      factor matrices, then the 2D spectral function is built. The Lagrange multiplier 
      method is used to obtain a one-dimensional spectral function, reducing complexity 
      for estimating the direction of arrival (DOA). The vector of the transmitter is 
      obtained by the partial derivatives of the Lagrangian function, and its 
      rotational invariance facilitates target range estimation. The method 
      demonstrates improved operation speed and decreased computational complexity with 
      respect to the classic Higher-Order Singular-Value Decomposition (HOSVD) 
      technique, and its effectiveness and superiority are confirmed by numerical 
      simulations.
