This letter addresses the detection problem of dim maneuvering targets in the presence of range cell migration. Specifically, it is assumed that the moving target can appear in more than one range cell within the transmitted pulse train. Then, the Bayesian information criterion and the generalized likelihood ratio test design procedure are jointly exploited to come up with six adaptive decision schemes capable of estimating the range indices related to the target migration. The computational complexity of the proposed detectors is also studied and suitably reduced. Simulation results show the effectiveness of the newly proposed solutions also for a limited set of training data and in comparison with suitable counterparts.

相邻距离单元格中暗淡机动目标的自适应检测

这封信解决了在存在距离细胞迁移的情况下暗淡机动目标的检测问题。具体而言，假设运动目标可以出现在发射脉冲序列内的一个以上的距离单元中。然后，联合利用贝叶斯信息准则和广义似然比检验设计程序，提出了六种能够估计与目标偏移有关的范围指标的自适应决策方案。还对所提出的探测器的计算复杂度进行了研究，并适当降低了这些复杂度。仿真结果表明，与有限的训练数据相比，新提出的解决方案对有限的训练数据的有效性。
