Abstract

Space is becoming increasingly congested and contested, which calls for effective means to conduct effective monitoring of high-value space assets, especially in Space Situational Awareness(SSA) missions, while there are imperfections in existing methods and corresponding algorithms. To overcome such a problem, this letter proposes an algorithm for accurate Connected Element Interferometry(CEI) in SSA based on more interpolation information and iterations. Simulation results show that:(i)after iterations, the estimated asymptotic variance of the proposed method can basically achieve uniform convergence, and the ratio of it to ACRB is 1.00235 in δ0 ∈ [-0.5, 0.5], which is closer to 1 than the current best AM algorithms; (ii)In the interval of SNR ∈ [-14dB, 0dB], the estimation error of the proposed algorithm decreases significantly, which is basically comparable to CRLB (maintains at 1.236 times). The research of this letter could play a significant role in effective monitoring and high-precision tracking and measurement with significant space targets during futuristic SSA missions.

一种用于重要空间目标高精度监测的频率估计算法

空间日益拥挤和竞争，需要有效手段对高价值空间资产进行有效监测，特别是在空间态势感知任务中，而现有方法和相应算法存在缺陷。为了克服这一问题，本文提出了一种基于更多插值信息和迭代的SSA精确连接元干涉(CEI)算法。仿真结果表明:(i)迭代后，所提方法的渐近方差估计基本能达到一致收敛，其与ACRB的比值在δ0∈[-0.5,0.5]处为1.00235，比目前最佳调幅算法更接近于1;(ii)在信噪比∈[-14dB, 0dB]区间内，本文算法的估计误差显著减小，与CRLB基本相当(保持在1.236倍)。这封信的研究可以在未来SSA任务中有效监测和高精度跟踪和测量重要空间目标方面发挥重要作用。
