论文摘要
噪声雷达可以通过相关系数来理解其检测性能。尽管文献中的大多数结果是根据信噪比（SNR）表示的，但我们表明，可以根据相关系数进行性能预测。为此，我们得出了相关系数的范围依赖性。然后，我们将结果与相干噪声雷达的接收器工作特性（ROC）曲线的先前衍生的表达相结合，这表明我们可以获得不同范围的ROC曲线。使用相干整合的常规雷达的相应结果比较表明我们的结果是明智的。我们工作的目的是证明相关系数是SNR了解雷达性能的可行辅助。
Noise radars can be understood in terms of a correlation coefficient which characterizes their detection performance. Although most results in the literature are stated in terms of the signal-to-noise ratio (SNR), we show that it is possible to carry out performance prediction in terms of the correlation coefficient. To this end, we derive the range dependence of the correlation coefficient. We then combine our result with a previously-derived expression for the receiver operating characteristic (ROC) curve of a coherent noise radar, showing that we can obtain ROC curves for varying ranges. A comparison with corresponding results for a conventional radar employing coherent integration shows that our results are sensible. The aim of our work is to show that the correlation coefficient is a viable adjunct to SNR in understanding radar performance.
