Abstract

Mobile source tracking is an important topic in the field of radio monitoring. A direct position determination method based on particle filtering is proposed in this letter for tracking multiple co-channel mobile transmitters. The co-channel signals, which have different symbol rates, overlap in both the time and frequency domains but can be distinguished in the cyclic frequency domain. We determine the positions of mobile targets directly from different cyclic cross-spectrum slices without time difference of arrival (TDOA) measurements. The particle filtering technique is employed to improve the accuracy in estimating motion states. Simulation results are given to demonstrate that the proposed algorithm outperforms other mobile tracking algorithms in the presence of co-channel interference.

不同循环频率同信道运动源的直接跟踪

移动源跟踪是无线电监测领域的一个重要课题。本文提出了一种基于粒子滤波的直接位置确定方法，用于跟踪多个同信道移动发射机。具有不同符号率的同信道信号在时域和频域中重叠，但可以在循环频域中区分。我们直接从不同的循环交叉频谱切片中确定移动目标的位置，而无需时差（TDOA）测量。采用粒子滤波技术来提高运动状态估计的准确性。仿真结果表明，在存在同信道干扰的情况下，该算法优于其他移动跟踪算法。
