Spatial Localization of Quasi-Stationary Targets Using Bistatic MIMO Radar
Quasi-stationary targets (QST) represent a class of nonstationary targets in which the statistics of their echoes are locally static over a short period of time, but exhibit differences from one local time frame to another. A novel algorithm is proposed for spatial localization of quasi-stationary targets using bistatic MIMO radar. The proposed algorithm exploits the character of quasi-stationary targets and the rotational0 invariance property of ESPRIT to estimate the two-dimensional direction of departures (2-D DODs) and two-dimensional direction of arrivals (2-D DOAs) of quasi-stationary targets, so the targets can be localized in a 3-D plane. The algorithm does not refer to multi-dimensional nonlinear peak search, so that the computational load of the algorithm is low, and the estimated parameters of the targets can be paired automatically. The theoretical analysis and simulation results show the proposed method is effective.
