Abstract

Multistatic localization, a passive positioning system, is widely used in low-altitude economy and related fields. However, base station position errors directly affect target position accuracy. To address this issue, on the basis of the existing model, a calibration target is introduced as an auxiliary measure to improve the Cramer-Rao Lower Bound (CRLB) of the system. This paper proposes a low-complexity two-step estimation method. First, a closed-form solution is constructed to estimate the base station position errors. Second, a semidefinite programming problem is formulated using the corrected results to analytically determine the target position. Simulation results show that the introduction of the calibration target improves the estimation accuracy by approximately 5 dB, and the performance of the proposed method is within 0.1 dB of the CRLB.
