利用相关系数预测相干噪声雷达性能

Performance Prediction for Coherent Noise Radars Using the Correlation Coefficient

David Luong, Bhashyam Balaji, Sreeraman Rajan

摘要:

噪声雷达可以根据表征其检测性能的相关系数来理解。虽然在文献中的大多数结果中所述的信号噪声比(SNR),我们表明,它是可以进行性能预测的相关系数。为此,我们推导出相关系数的范围依赖性。然后,我们将我们的结果与先前推导出的表达式的接收机工作特性(ROC)曲线的相干噪声雷达,表明我们可以获得ROC曲线的变化范围。与采用相参积累的常规雷达相应结果的比较表明,我们的结果是合理的。我们的工作的目的是表明,相关系数是一个可行的辅助信噪比在理解雷达性能。

英文摘要:

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.
