This paper delves into the problem of moving-target detection in partially homogeneous environments (PHE) with unknown Gaussian disturbance using a frequency diverse array multiple-input multiple-output (FDA-MIMO) radar. Using training data, we have derived expressions for four adaptive detectors, including one-step and two-step generalized likelihood ratio test (GLRT), Rao (TRao) test, Wald (TWald) criteria, respectively. All proposed detectors are characterized by constant false-alarm rate (CFAR). The theoretical analysis simulation results validate effectiveness detectors.
