摘要

本文解决了前向散射雷达（FSR）在被测数据（DUT）与辅助数据之间存在噪声功率不匹配时检测运动目标的问题。为了对这种不匹配进行建模，假设DUT中的噪声功率和辅助数据中的噪声功率存在噪声标度因子的差异。在DUT已知和未知噪声功率下，设计了两种FSR自适应运动目标检测器。性能评价表明，该检测器具有较好的检测性能，特别是在噪声比例因子较大的情况下。

Adaptive Moving Target Detection for Forward Scatter Radar When the Noise Power Mismatch Occurs

This letter addresses the problem of detecting moving targets with forward scatter radar (FSR) when the noise power mismatch between the data under test (DUT) and the secondary data occurs. To model such mismatch, it is assumed that the noise power in the DUT and the noise power in the secondary data differ by a noise-scaling factor. Under both known and unknown noise power of the DUT, two kinds of adaptive moving target detectors for FSR are designed. The performance evaluation indicates that the proposed detectors have better detection performance than their counterparts, especially when the noise-scaling factor is large.
