摘要

本文推导了相位/幅度编码雷达信号在空间白色分布瑞利杂波存在下的内曼-皮尔逊离散时间检测器。我们考虑处理相对于脉冲持续时间较长的数据记录。对于几种实际感兴趣的波形，推导并计算了最佳检测器的性能增益优于标准相关器的测量。在杂波受限的情况下，空间分布的瑞利杂波的检测性能几乎与波形编码无关。最后一个结果允许人们将该探测器与非编码脉冲雷达一起使用，并在所有其他参数保持不变的情况下实现与脉冲编码雷达相似的检测性能，因为杂波占主导地位噪声。

Detection in distributed Rayleigh clutter

This paper derives the Neyman-Pearson discrete-time detector for phase/amplitude coded radar signals in the presence of spatially-white distributed Rayleigh clutter. We consider processing of data records which are long relative to the pulse duration. A measure of the optimum detector's performance gain over that of a standard correlator is derived and calculated for several waveforms of practical interest. It is also shown that for the clutter-limited case that the detection performance in spatially-distributed Rayleigh clutter is virtually independent of waveform coding. This last result allows one to use this detector with a non-coded pulse radar and achieve similar detection performance to that of a pulse coded radar when all other parameters are held constant provided as the clutter dominates the noise.
