摘要

在雷达探测系统中，多脉冲传输通过对接收时脉冲回波进行积分来提高探测性能。在本文中，我们推导了考虑均匀伽马分布雷达杂波应用于MP情况下的单元平均虚警概率PFA的封闭表达式——虚警率恒定，CFAR的最大值和CFAR的最小值。用解析公式给出了对应于实际情况的正实形参数表达式，并用检测阈值计算值T与蒙特卡罗模拟结果进行了比较，验证了表达式的正确性。关键词:多重脉冲- cfargo - cfarso - cfargamma分布式杂波披露声明作者未报告潜在的利益冲突。

Closed-form expressions of P _FA of mean level CFAR detectors for multiple-pulse gamma-distributed radar clutter

ABSTRACTIn a radar detection system, multiple pulse (MP) transmission is used to improve detection performance compared to the single pulse case by integrating the echoes of pulses at reception. In this paper, we derive closed-form expressions of the probability of false alarm PFA of the cell averaging-constant false alarm rate, greatest-of CFAR, and smallest-of CFAR detectors considering a homogeneous gamma distributed radar clutter applied to the MP case. Expressions are given by analytical formulas for a positive real shape parameter which correspond to a real situation and are validated by comparing them in terms of the detection threshold calculated values T, to the results obtained by means of Monte Carlo simulations.KEYWORDS: Multiple pulsesCA-CFARGO-CFARSO-CFARgamma distributed clutter Disclosure statementNo potential conflict of interest was reported by the author(s).

期刊介绍： Remote Sensing Letters is a peer-reviewed international journal committed to the rapid publication of articles advancing the science and technology of remote sensing as well as its applications. The journal originates from a successful section, of the same name, contained in the International Journal of Remote Sensing from 1983 –2009. Articles may address any aspect of remote sensing of relevance to the journal’s readership, including – but not limited to – developments in sensor technology, advances in image processing and Earth-orientated applications, whether terrestrial, oceanic or atmospheric. Articles should make a positive impact on the subject by either contributing new and original information or through provision of theoretical, methodological or commentary material that acts to strengthen the subject.
