“…The mean-square error (MSE) of the maximum likelihood estimator (MLE) is close to the CRLB when the high signal-to-noise ratio (SNR) is satisfied. It is also worth mentioning that the performance of multiple signal classification (MUSIC) in computational time-reversal (TR) applications is studied in [13,14], where the closed-form MSE matrix of TR-MUSIC is calculated for the single-frequency case in multistatic co-located and non co-located scenarios. Simulation results show that TR-MUSIC can predict a more accurate MSE than CRLB, while it is a sub-optimal estimator since it does not asymptotically achieve the CRLB as the MLE.…”

“…Simulation results show that TR-MUSIC can predict a more accurate MSE than CRLB, while it is a sub-optimal estimator since it does not asymptotically achieve the CRLB as the MLE. In the last couple of years, there is a growing interest on the CRLB studies for the target estimation performance of distributed radar networks [11,12,13,14,15,16,17,18,19]. The authors in [11] derive the analytical expressions of CRLB for both noncoherent mode and coherent mode in MIMO radar systems, which shows that the CRLB is inversely proportional to the carrier frequency and signals averaged effective bandwidth.…”

“…Notice that the estimation of EDB is essentially equivalent to the determination of the aliasing number. Afterwards, we calculate the equivalent parameter F p by means of spatial spectrum estimation methods which have been widely used in generic imaging problems [27][28][29]. If there exist redundant channels, the idea of subspace-based methods can be utilized [30,31]; otherwise, we use the Capon estimator [14,21].…”

“…However, theoretical analysis and simulation results show that subspace methods usually exhibit a certain performance loss in estimating locations of highly correlated signals [6]. Results in [7,8] demonstrate that subspace methods may also suffer from performance loss in active localization scenarios. Using the structure of uniform linear array (ULA) array manifold, the authors of [9,10] have proposed an iterative quadratic maximum likelihood (IQML) method to solve the ML problem.…”
