海杂波中广义符号恒虚警检测算法性能分析

Performance Analysis of Generalized Sign CFAR Detection Algorithms Within Sea Clutter

摘要:

分析了广义符号检测算法在仿真的高斯杂波背景和实测海杂波背景下,对2种目标(Swerling 0型和Swerling II型)的检测性能,以及对实际渔船目标的检测性能。研究表明,随着脉冲数、参考单元数和信杂比的提高,该检测算法的检测性能有所提高；在低信杂比条件下,GS检测算法对Swerling II型目标的检测性能优于对Swerling 0型目标的检测性能,在高信杂比的条件下,对Swerling 0型目标的检测性能优于对Swerling II型目标的检测性能。

Abstract:

The performance of GS detector for two kinds of target (Swerling 0 and Swerling II) was studied under Gaussian clutter and real sea clutter. The analysis results showed that, with the numbers of pulse, reference cells and signal-to-clutter ratio (SCR) increasing, the performance of GS detector rose. In the condition of low SCR, the performance of GS detector detecting Swerling II targets was better than that of GS detector detecting Swerling 0 targets; and in the condition of high SCR, the performance of GS detector detecting Swerling 0 targets was better than that of GS detector detecting Swerling II targets.
