Under narrowband signal and array assumptions, the maximum likelihood estimations (MLE) for target parameters in the adaptive radar with uniform planar array (UPA)weve analyzed. The UPA model was analyzed, and then the ML estimators for target parameters and the corresponding CRB were given. By means of Jacobian matrix, the CRBs for target elevation, azimuth, velocity, and magnitude, and phase were derived. The results are an extension from 1-D ULA to 2-D UPA, which can be applied to the performance evaluation for parameter estimation of airborne moving target.
